**KEY TOPICS**

** Problem 1CQ: Can kinetic energy ever be negative?** Can gravitational potential energy ever be negative? For each, give a plausible reason for your answer without making use of any equations. [1] At D, the ball had kinetic energy but no (gravitational) potential energy as it was at the ground level. [2] If you suddenly release the body, this potential energy will again be converted, but this time into kinetic energy (the object will gain velocity as it falls). [3] Potential energy can be converted to the kinetic energy of movement when an object falls from a higher GPE location or there is no counter force holding a stretched or compressed spring in place. [4]

The conservation of mechanical energy and the relations between kinetic energy and speed, and potential energy and force, enable you to deduce much information about the qualitative behavior of the motion of a particle, as well as some quantitative information, from a graph of its potential energy. [5] You can find the values of (a) the allowed regions along the x-axis, for the given value of the mechanical energy, from the condition that the kinetic energy can’t be negative, and (b) the equilibrium points and their stability from the properties of the force (stable for a relative minimum and unstable for a relative maximum of potential energy). [5]

By lifting it, the object gains potential energy (not kinetic energy). [3] It has less kinetic energy when it is at the top of the arch, this is stored as potential energy relative to the Earth’s gravitational field, and re-converted to kinetic energy on the way down. [2] @Javier Right, but that can’t be explained by elementary physics right? I mean, I believe that the ball would have no kinetic nor potential energy, but it would shoot up because of the energy stored in the compressed fibers of the ball (right?). [2] Kinetic energy is energy of motion, while potential energy is energy of position. [6] Then it starts expanding again, and the potential energy is again turned into kinetic energy. [2]

Using an example, a 10 kg object at rest on the ground (r0) has zero Kinetic and Potential Energy (simple model). [3] This assumption implies that the particles possess no potential energy and thus their total energy is simply equal to their kinetic energies. [7] Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. [6] Mechanical Energy – Mechanical energy is the sum of the kinetic and potential energy of a body. [6] A swinging pendulum has both kinetic and potential energy, thermal energy, and (depending on its composition) may have electrical and magnetic energy. [6]

What do you do to get there? You add kinetic energy to your system, so it rises up the potential well. [8]

The short version is that when an object falls toward Earth, it gains speed and momentum, and its kinetic energy increases as its gravitational potential energy falls, but this explanation skips many important details. [9] The gravitational potential energy an object has at the start of a fall is converted into kinetic energy as it falls, and this kinetic energy goes into producing sound, causing the object to bounce, and deforming or breaking the object as it strikes the ground. [9] In the absence of air resistance, which causes some energy to be lost, the kinetic energy just before the object strikes the ground would be the same as the gravitational potential energy it had at its highest point. [9] When the object is released, the gravitational potential energy is gradually converted into kinetic energy as it picks up speed. [9] The initial kinetic energy, the gravitational potential energy is negative gravitational constant times the mass of the planet times the mass of your little gas molecule divided by the radius of the planet. [10] The investigation in this activity allows students to explore energy transfer, the relationship of gravitational potential energy to mass and height, and the transformation of potential energy to kinetic energy. [11] At the surface of X it has some initial kinetic energy and it has some initial potential energy due to the gravitational interaction with planet X. Then what’s going to happen is does that molecule escape? Well in order to know if it escapes, here’s X, It has to get very, very, very far away, here’s our molecule, from X. So far that there is no interaction. [10] Basically what kinetic energy can what energy conservation is going to say is that the initial kinetic energy plus the initial potential energy is going to equal zero. [10] If you launch a rubber band across the room, the potential energy is converted to kinetic energy, the energy of motion. [12] When you release it the rubber band starts to unwind, and the potential energy is converted to kinetic energy as the car is propelled forward. [12]

The potential energy of an apple will immediately transform to kinetic energy once the apple is cut loose from the apple tree. [13] The potential energy that results when two or more atoms bond will immediately transform to kinetic energy once the atoms separate and begin to move away from one another. [13] Weave popsicle sticks together to build potential energy before releasing them in a flurry of kinetic energy. [14]

** Mechanical energy is the sum of all of the potential energies and kinetic energies in an object.** [4] You are quite right in saying that the net work done on the object by the force that you exerted on the object and the gravitational force that the Earth exerted on the object is zero and hence the change in kinetic energy of the object is zero. [3] The kinetic energy is 0 even after you did work on it, is because gravitational force did equal and opposite work on it I.e. negative work. [3]

If we lift and object up, the net work is clearly zero because the kinetic energy after the lift and before the lift are the same (0). [3] At the maximum height, the kinetic energy and the speed are zero, so if the object were initially traveling upward, its velocity would go through zero there, and y max would be a turning point in the motion. [5] Since the lowest energy an object can have is when it has no speed, there cannot be any lower value for kinetic energy than zero. [1] Since the velocity of the object is zero both before and after raising the object, you are correct that the kinetic energy is zero in both cases. [3] When an object enters Earth?s gravitational field, kinetic energy is released while the mass of the object doesn?t change to reflect this gained energy. [8] This means each of it?s FSP have more energy than that of Earth FSP. The gravitational field of the falling object starts to lose some of its energy which gets converted to kinetic energy. [8] If you threw the ball, directly up, it would have zero motion at the vertex, and the closed chemical system will have no kinetic energy relative to the Earth’s gravitational field. [2] If the ball was moving purely vertically, it would have zero kinetic energy at D also, assuming D means the moment where the ball is at maximum compression. [2] The kinetic energy is zero only when the ball is stationary, and the ball is stationary only at E: so this is the only point where the kinetic energy is zero. [2] At the point of maximum compression there is no kinetic energy, the ball stands still. [2] When the ball hits the ground, it starts with kinetic energy due to moving downwards. [2] Ignoring the “complicated” fact that anything with heat has kinetic energy internally, is there some reason the ball wouldn’t continue to have kinetic energy? There is no longer vertical motion, but it is still in forward motion. [2] The air molecules inside the ball also have kinetic energy, their motion and their collisions with the inside of the ball is what maintains the shape. [2] One type of energy is the energy an object in motion would have–we call this kinetic energy. [15] What happens to the kinetic energy of an object (like a bullet) when it collides with something (like Black Panther’s super suit)? If the bullet slows down, then its kinetic energy must decrease. [15] The kinetic energy depends on both the mass and the velocity of the object. [15] The opposite takes place, when the kinetic energy is used to lift an object. [8] Kinetic energy is equal to one-half mass times velocity squared. [3] This also implies that the total kinetic energy of the spinners is equal to the total energy of the universe. [8] In a closed system, the total energy is constant such that this decrease in kinetic energy must be accompanied by an increase in some other type of energy (like thermal energy). [15] Kinetic energy cannot ever be negative because it is defined as the energy of motion. [1] The highest point of motion kinetic energy is at the way bottom of the hill right when you are about to stop. [16] If it has kinetic energy at D then it has kinetic energy at B. There is component of motion in the X direction. [2] There is a question and answer that indicates that a airborne ball at the top of the trajectory does not have kinetic energy. [2] At E, the ball stopped moving, so it had no kinetic energy. [2] As other have stated, the only state where it has no kinetic energy is E, UNLESS the ball is considered to only move in the vertical direction (in which case, the ball has no kinetic energy at B). [2] As Javier mentioned, the ball would’ve had no kinetic energy at D if this only represented vertical displacement. [2] If the ball is kicked in any direction except perfectly vertical, it has kinetic energy throughout its flight since it never stops moving horizontally. [2] There is no net loss or gain of kinetic energy when particles collide. [7] The flux lines of the magnetic field density is determined by the applied kinetic energy of the magnet and the distance between the magnetic poles. [8] The average kinetic energy is the same for all gases at a given temperature, regardless of the identity of the gas. [7] The ball’s surface will also sublimate, even at cold temperatures, as a result of it’s random local kinetic energy. [2] This kinetic energy is proportional to the absolute temperature of the gas. [7] This may also suggest that the constant speed of light and the entire universe energy are both derived from the spinning kinetic energy of the singularities. [8] However there is one condition where B could have zero kinetic energy. [2] Yes the Black Panther could use the kinetic energy from those bullets to charge two iPhones. [15] A bullet has significantly more energy–but is it enough to be useful? If I had to estimate (and apparently I do), I would guess about 20 bullets hit Black Panther, so that would be on the order of 40,000 Joules of kinetic energy from the bullets. [15] Everyone knows that the Black Panther isn’t going to use the kinetic energy charge his phone. [15] With this, I can calculate the kinetic energy of one bullet. [15] For now, I’m just going to assume all of this kinetic energy gets converted into the energy in the suit (it’s super advanced so it can do that). [15]

When you exert a force which is external to the object & Earth system and do work separating the object and the Earth the object & Earth system gains gravitational potential energy. [3] If you are on Earth, the only place where you have zero gravitational potential energy is infinitely far away from Earth (and the sun etc etc). [8] If we use the gravitational potential energy reference point of zero at y 0, we can rewrite the gravitational potential energy U as mgy. [5] The object alone has been treated as a system and that object alone cannot have gravitational potential energy. [3] According to current literature, gravitational energy is the potential energy a body with mass has in relation to another massive object due to gravity. [8] E mgh (where E is the potential energy, m is mass and h is the vertical distance from the massive object). [8] The mechanical energy of the object is conserved, E K + U, and the potential energy, with respect to zero at ground level, is U(y) mgy, which is a straight line through the origin with slope mg. [5] The potential energy at any point in its path is gh, where h is how high from a reference, the ground in this case, the ball is at any given time and g, gravity. [2] As for potential (gravity) energy, if considering the ground as the “absolute” level 0, then it has none, but, obviously, if someone was to dig a hole under the ball, it would fall. which indicates that it DOES have potential energy (but that the energy cannot be converted, as the ball cannot fall), rather than having none at all. [2] That energy is converted into potential energy (like a spring) when the ball hits the ground and gets compressed. [2] The ball also had not (gravitationa) potential energy as it was at ground level. [2] A ball sitting on a table has potential energy with respect to the floor because gravity acts upon it. [6] If the potential energy of the earth surface is not considered to be zero rather if we consider a man at a height of 1km above the surface then potential of earth will be negative w.r.t that person. [8] For eg: potential energy of a spring is considered to be zero at its natural length because it has no ability to do any work but zero potential energy can be chosen at any length and with respect to that length potential energy that spring can be calculated at any length and if the new length chosen as zero potential energy then spring having less ability to do work than that spring will have negative potential energy w.r.t the 1st one. [8] The negative work done by such forces gets stored as potential energy. [3] We saw earlier that the negative of the slope of the potential energy is the spring force, which in this case is also the net force, and thus is proportional to the acceleration. [5] Planets being in gravitational field of Sun, have negative potential energy. [8] Conservation of energy requires that this gravitational field energy is always negative.The gravitational potential energy is the potential energy an object has because it is within a gravitational field. [8] Current literature rationalize that by saying the gravitational fields have negative energy when they try to explain gravitational potential energy. [8] Of course, gravitational potential energy is the kind we’re considering vs. stored energy from the kick or bounces. [2] When the cart is getting higher and higher, gravitational potential energy. [16] @Ant it has elastic potential energy, but not gravitational potential energy. [2] The potential energy for a particle undergoing one-dimensional motion along the x-axis is U(x) 2(x 4 − x 2 ), where U is in joules and x is in meters. [5] Before ending this section, let’s practice applying the method based on the potential energy of a particle to find its position as a function of time, for the one-dimensional, mass-spring system considered earlier in this section. [5] It’s velocity at the maximum height is zero, as the energy over here has become potential energy. [2] Potential energy is a relative concept which depends on the frame of reference which has been chosen as zero potential. [8] Substitute the potential energy U into Equation 8.14 and factor out the constants, like m or k. [5] If I want to lift something up off the ground (like a textbook or a car), I can calculate another kind of energy–gravitational potential energy. [15] Whether they are in motion or stationary, they also have potential energy because they are on a table above the ground. [6] When you throw a stone up in air, it gains positive potential energy (m g h) considering ground as origin. [8] Potential Energy – This is energy due to an object’s position. [6] This is true for any (positive) value of E because the potential energy is unbounded with respect to x. [5] Elastic potential energy is what is stored in a spring or spring-like material when it’s stretched or compressed relative to its rest length. [4]

This kit introduces students to the concepts of kinetic and gravitational potential energy and the conversion of one form of energy into another. [11] The total energy in a substance is usually equal to the sum of kinetic plus potential energy. [13] From figure 1, energy can exist as kinetic and potential energy. [13]

The key to the popsicle stick chain-reaction comes from potential (or stored) energy in the over/under weaving and kinetic (or motion) energy in the release. [14]

Specifically it stores elastic potential energy–the type of energy stored when a material is deformed (as opposed to gravitational potential energy, the type you get when you raise an object off the ground). [12] An apple hanging up on a tree has potential energy due to the earth?s gravitational pull on it. [13] Now the gravitational potential energy we can easily solve for. [10] No interaction means that that final potential energy is zero. [10] Chemical potential energy can exist as intermolecular and intramolecular forces. [13] The more you stretch the rubber band, the more potential energy is stored, and the farther and faster the car should go. [12] When you wind up the car’s axle you stretch the rubber band and store potential energy. [12]

If you end with zero it means you had just enough to overcome the gravitational interaction and if you have less than that, that means you don’t have enough to overcome gravity and you’re going to stop short when you run out of kinetic energy before you get infinitely far away, before you escape that interaction. [10] If you had more kinetic energy left over that means that when you started you had more than enough kinetic energy to overcome the gravitational attraction. [10] What’s the temperature of the gas? It’s average kinetic energy per 100 molecules so the average kinetic energy per 100 molecules is 1 times 10 to the -19 joules so each molecule has 1 100th of that total kinetic energy So that means that we have to drop that 10 to the -19 down by another 100th which is 2 decimal points. [10] Recall that the definition of the average kinetic energy is just 1 half times M times the average of the square of the speed. [10] For the average kinetic energy you don’t use the average of the speed you actually use the average of the square of the speed. [10] The RMS value we use a lot because it’s actually really really easy to find since we have that relationship between temperature and kinetic energy it’s super easy to find the RMS speed it just comes out naturally. [10] The thermal kinetic energy is 3 halves K times the temperature. [10] The temperature is just 2 thirds, 1 times 10 to the -21, which is the kinetic energy per individual molecule not per 100 molecules divided by the Boltzmann constant which is 1.38 times 10 to the -23 and this whole thing comes out to 4831 Kelvin. [10]

As two such massive objects move towards each other, the motion accelerates under gravity causing an increase in the positive kinetic energy of the system. [17] When the object hits the ground, the kinetic energy has to go somewhere, because energy isn?t created or destroyed, only transferred. [9] What does it mean to escape gravity? Well here’s the surface of X where X has some radius R of X and there’s a particle that’s going to have some kinetic energy. [10] We measure the thermal energy and if it’s greater that this minimum escape kinetic energy then planet X can’t have an atmosphere. [10] All of this tells us there our initial kinetic energy has to be at least 1.09 times 10 to the -19 jewels OK. So now the question is what is our thermal energy? That was the hint. [10] This becomes 2 thirds N times that average kinetic energy or 3 halves PV over N is the average kinetic energy. [10] A gas of molecular nitrogen has an average kinetic energy per 100 molecules of 1 times 10 to the -19 joules. [10] Remember guys that our relationship between the average kinetic energy and the temperature is 3 halves KT. This we found in a previous video on the kinetic theory and temperature. [10] This is 10 to the -21 joules alright and from our relationship between the average kinetic energy and the temperature of the gas, we can solve for that temperature which is exactly what the question is asking for. [10] Substituting this into our equation of state we can write PV in terms of the average kinetic energy. [10] If I take the kinetic energy and I just average it 1 half doesn’t average, it stays 1 half. [10] This issue can only be resolved if the change in gravitational energy is negative, thus cancelling out the positive change in kinetic energy. [17] Now in order to just have enough kinetic energy to escape, the kinetic energy final would also be zero. [10] We can say that our initial kinetic energy just has to equal G capital MX little M over RX. If the kinetic energy equals at least this, it can escape gravity if it’s greater than this it can escape gravity and then keep going forever if it’s less than this it’ll run out of kinetic energy short of escaping gravity. [10] Kinetic energy is the energy something has because of its motion. [13] Notice this though, what does this look like? This looks exactly like a kinetic energy. [10] That thermal kinetic energy is less than the required escape kinetic energy. [10] In real cars, gasoline’s chemical energy or the electrical energy in a battery is converted to kinetic energy of the moving car. [12]

“Credentials are like potential energy, the compliments of a name on paper, in documents, word of mouth, but faith is like kinetic energy, the motion and the force that which is witnessed. [18] “With a, you start from a disordered state, where kinetic energy is greater than potential energy,” said Xuedong Hu, a professor of physics at the University at Buffalo. [19] We imagine that the primed coordinates are the body coordinates and the unprimed coordinates are the inertia coordinates; therefore, it is straightforward to write the kinetic energy in the primed coordinates and the potential energy in the unprimed coordinates. [20]

Work is done on an object by applying force, and the object speeds up and thus gains kinetic energy. [21] The energy added to an object to take it from an initial speed of zero to a final speed of something is its kinetic energy. [22] The kinetic energy of an object is the energy that it possesses due to its motion. [21] Let’s calculate the kinetic energy of a mass in rigid body motion. [20] What will happen when a ball fall down and I know that it turns into kinetic energy but when it hits the. [21] Example of kinetic energy: In billiards, a player gives the cue ball kinetic energy when he strikes the ball with the cue. [23] When the ball comes into contact with another ball, it transmits its kinetic energy, allowing the next ball to be accelerated. [23] Now if there are no forces on the body, the kinetic energy of the body is conserved. [20] Because the primed frame is fixed to the body, the moments of inertia in the kinetic energy are constant with time. [20] The first form is useful to visualize what the body is doing, while the second form is good for calculating the kinetic energy because we have used the primed coordinate system to characterize the location of the principal axes of the body. [20] The first term is the classical equation for kinetic energy. [22]

Potential energy is the energy of motion, i.e., there is potential energy in sugar, when you consume. [23] Example of potential energy: The roller coaster has the greatest potential energy when it is stopped at the top of a big drop. It has the potential to roll down the hill, but it has not yet begun moving. [23] The roller coaster also demonstrates potential energy when it is stopped, allowing individuals to enter or exit the ride. [23]

**POSSIBLY USEFUL**

** I would like to better understand how physics explains the continuous “work” required to maintain the potential (gravitational) energy at a stationary height.** [3] If the ball were kicked straight up, at the apogee its energy would be all potential since it’s not moving horizontally or vertically, it stops momentarily. [2] The particle in this example can oscillate in the allowed region about either of the two stable equilibrium points we found, but it does not have enough energy to escape from whichever potential well it happens to initially be in. [5]

Most of the hadrons? mass is due to the borrowed energy from the VSP. The borrowed energy to form the confinements and the gluons turn the adjacent VSP (due to the reduced energy and rotational momentum radii) to spinning balls of energy which make up the limited number of the gravitational flux lines (GFL) associated with the creation of each planck mass. [8] The observed pulling down by gravity is in reality the gravitational flux lines powered by the spinning balls of energy act as vertically oriented moving belts accelerating towards the centre of the mass. [8] Therefore the gravitational acceleration toward the centre of the mass is determined by both the increase in number and speed of the spinning balls of energy per planck square area. [8] This what what turns the VSP into the gravitational spinning balls of energy with increasing speed. [8] This borrowed energy leads to loss of energy by the vacuum which leads to contraction of the vacuums? bubbles of energy and get them turned into spinning balls which make up the vector oriented gravitational flux lines. [8]

According to our above explanation, the change in local curvatures are due to the gravitational FSP having radii lower than the radii associated with VSP. The change in local energy momentum is due to the drop in the amount of energy and increase in their rotational angular momentum due to c/rfsp is greater than c/ rvsp. [8] Einstein expressed this process by saying that the changes in local spacetime curvature with local energy and momentum lead to increase in stress-energy tensor density of flux and momentum. [8] Any change in the value of the radius of a space particle would lead to a change in the rotational angular momentum of the energy could of the SP. [8] The drop in the VSP energy means that the gravitational field space particles (FSP or the spinning balls of energy) would have reduced radii and increased rotational angular momentum, hence the expression by Einstein of “stress-energy-tensor”. [8] Once the falling object reaches Earth?s surface, its gravitational field space particles will have the same (reduced) energy level. [8] When you lift an object on the Earth, the energy is strictly stored in the gravitational field. [3] GPE is the energy stored in an object based on its distance above a zero-GPE reference point. [4] If additional energy is supplied to the object, it actually increases that object’s mass. [6] The creation of a planck mass is the trigger for the creation of the GFL, which are made of spinning quantum balls of energy with increasing speed as they approach the centre of the relevant mass. [8] The gravitational force is not an act of “pushing” or “pulling” but an “act of being on a spinning network of quantum balls of energy vertically oriented toward the center of the gravitational field”. [8] The Strings theory is also recognized in this work through the process of coupling and decoupling of the strings of energy which leads to the emissions and absorptions of the gravitons, which are responsible for reshaping the geometry of the gravitational field and the creation of the spinning loop networks. [8] The assumed vacuum has all of the properties that a particle may have such as spin, energy, magnetic moments, etc. On average, most of these properties cancel out due to the equal number of singularities which are spinning CW & ACW, and the equal number of strings with left handed and right handed helicities. [8] A “field” is filled with FSP (spinning quantum balls of energy). [8] Creation of mass involves borrowing energy to create the quantum fields of the electrons and quarks and the creation of confinements with its gluons. [8] Where is that continuous energy requirement being accounted for? Molecular and environmental heat, relativistic mass gain and loss? I know that I wouldn’t be able to hold 10 kg above my head for long even though the standard calculation would say that, theoretically, no further work is required once height is reached. [3] Work (the energy expended) is equal to force times distance. [3] There may be overlap between forms of energy and an object invariably possesses more than one type at a time. [6] The energy that an object possesses because of its position on a gravitational field. [16] The mass-energy equivalence theory states an object at rest in a frame of reference has a rest energy. [6] The new theory on gravity which reconciles many aspects of the different theories dealing with gravity, states that vacuum is made of foam like bubbles of energy. [8] This has led us to the conclusion that fermion particles don?t get completely annihilated into pure energy but always end up with lighter fermion particles, like the almost massless neutrinos and antineutrinos, which are difficult to detect. [8] The coupling and decoupling forces also explain how virtual photons and gravitons are emitted and absorbed by the SP. – Strings of single helicity form the energy clouds of the fermion particles, and strings of both helictites form the energy clouds of the SP and the various bosons. [8] As VSP are the most common particles in the universe, we assume that, m mp, E Ep and r lp (where mp is planck mass, Ep is planck energy and lp is planck length). [8] How much energy could he get from these bullets? To estimate this, I need three things: mass of bullet, speed of bullet, and number of bullets. [15] As the rotational angular momentum of energy is constant at the speed of light divided by radius, then any drop in the length of the radius will lead to higher rotational angular momentum. [8] The varying rotational angular momentum of the energy cloud of the FSP are determined by the relationship c/ r. [8] It relates local spacetime curvature with its local energy and momentum. spacetime is expressed by the stress-energy tensor which describes the density and flux of energy and momentum within it. [8]

The gravitons? roles are restricted to the creation of spin networks, by redistributing the energy foams of the vacuum in the process of creating the gravitational flux lines. [8] Two billiard balls colliding, for example, may come to rest, with the resulting energy becoming sound and perhaps a bit of heat at the point of collision. [6] Since the centripetal force of all the spinners is constant, and Fc Ep/ lp, then any change in the energy of a space particle must lead to a corresponding change in its radius and the emission of virtual particles. [8] According the law Fc E/ r, the loss of energy by the adjacent VSP lead to changes in their geometry. [8] The changes in VSP energy lead to a change in the spinners/ density ratio of the SP (for short spinners? density). [8] The cool part is that this calculated value of energy doesn’t change for this closed system. [15]

Magnetic Energy – This form of energy results from a magnetic field. [6] The FSP density (spinners/strings ratio of the SP) of any field can be measured by the different accelerations of their energy clouds driven by the fixed number of their singularities. [8] The FSP become as if they are spinning balls of energy with different speed and specific vector orientation determined by the sources of the disturbances. [8] Einsteins general theory of relativity describes the fundamental interaction of gravitation as a result of spacetime being curved by mass and energy. [8] Where does this energy then come from? Hence they use the term “negative energy” in compliance with the conservation of energy law. [8] After “charging up” the suit, the Black Panther uses some type of energy burst to flip over a car. [15] I am going assume that the car moves up a distance of 3 meters and that all of this is done by the Black Panther energy thing. [15]

The horizontal component, on the other hand, is not zero, and keeps on decreasing, as energy is lost via heat energy. [2] In the graph shown in Figure 8.11, the x-axis is the height above the ground y and the y-axis is the object’s energy. [5] How does the Law of Energy Conservation explain the following scenarios: Skate park character reaching the same max height at both sides. [16] The skate park character will reach the same height at both sides because the drop is the same, and you can’t make energy, so there will be the same thing because both sides are identical. [16]

In this manuscript we suggest that at the heart of everything there is only two basic energy particles (BEP), and a relationship exist between them in line with the supersymmetry theoretical formulation. [8] Electrical Energy – This is energy from the movement of charged particles, such as protons, electrons, or ions. [6]

It’s important to keep in mind that just because energy exists, that doesn’t mean it’s necessarily available to do work. [6] Energy is defined as the capacity of a physical system to perform work. [6]

Such waves cause SP to lose energy in one direction perpendicular to the arrow of propagation while they gain energy and expand in the other direction. [8] The SP are foam-like bubbles of energy pressed into hexagon geometry by the centrifugal force of their singularities. [8] Other forms of energy may include geothermal energy and classification of energy as renewable or nonrenewable. [6] Since energy can’t be created and it can’t be destroyed, it’s transferred from one form to another. [4] When dealing with energy, it helps to be able to calculate the energy in different forms. [15]

What if you want to charge your smartphone? An iPhone battery has about 20,000 Joules of energy stored in it. [15] Energy was not cancelled, as you may have thought, but converted. [3] We are also assuming in the game that there is no friction in e skate park, while on the roller coaster there is more friction and the energy is being transformed. [16] A cart on a roller coaster has the most gravitational energy when it is at the highest point of the ride. [16] As a roller coaster cart is going up a hill, it gains more gravitational energy.

The higher an object is, the more gravitational energy it has. [16] When the cart is at its highest point, it has the most gravitational energy. [16]

In the case the Black Panther scene, it appears that the impact of the bullets lead to an increase in some type of stored energy in his suit (maybe like in a battery or something). [15] Just a few more bullets or some other stored energy to add to this and boom–you just flipped a car. [15]

As their temperature increases, their speed increases, and finally their total energy increases as well. [7] If you heat a steel bearing (adding thermal energy), you very slightly increase its mass. [6] The rollercoaster won’t reach the same height because it transforms into thermal energy through friction. [16] We note in this expression that the quantity of the total energy divided by the weight (mg) is located at the maximum height of the particle, or y max. [5] According to the law of conservation of energy, the total energy of a system remains constant, though energy may transform into another form. [6]

This is regarded as the negative energy associated with gravitational fields. [8] When two things rub against each other, they gain friction, so energy is transformed into thermal energy. [16]

In classical mechanics, two or more masses always have a gravitational potential. [8] Your graph should look like a double potential well, with the zeros determined by solving the equation U(x) 0, and the extremes determined by examining the first and second derivatives of U(x), as shown in Figure 8.13. [5] You can have a potential thats greater than where you declare zero to be, or less than where you declare it to be. [8]

The macroscopic phenomena of pressure can be explained in terms of the kinetic molecular theory of gases. [7]

** Before it falls – if we assume it?s stationary – the object possesses energy in the form of gravitational potential.** [9] When an object falls toward Earth, a lot of different things happen, ranging from energy transfers to air resistance to rising speed and momentum. [9] An alternative way to think about what happens as an object falls toward Earth is in terms of energy. [9]

In all real collisions, energy is lost when it hits the ground, some of it going into creating a sound and some going into deforming or even breaking the object apart. [9] If the collision is completely inelastic, the object is squashed or smashed, and all of the energy goes into creating the sound and the effect on the object itself. [9] If the collision is elastic, meaning the object can bounce, much of the energy goes into making it bounce up again. [9]

When they are infinitely far apart, the gravitational attraction and hence energy approach zero. [17] The gravitational attraction – and hence energy – also increase in magnitude, but the law of energy conservation requires that the net energy of the system not change. [17] Properties of matter change when its energy or temperature changes. [13]

Students design and conduct an experiment to quantitatively test how the variables of mass and height affect the energy carried by a metal cylinder. [11] Understanding all the factors at play prepares you for understanding a range of problems in classical physics, the meaning of terms such as momentum, and the nature of the conservation of energy. [9] Let?s use the following model to further illustrate the different forms of energy. [13] Your model car will use a rubber band as the source of energy. [12] To make the concept of energy easy to understand, we will use the word “flow.” [13]

Lawrence H. Ford and Thomas A. Roman; “Negative energy, wormholes and warp drive”, Scientific American January 2000, 282, Pages 46-53. [17] Non renewable energy sources can’t be renewed in our life time. [13] Although we can?t define energy like we did for an atom, we do know what it does. [13] Of these two forms, energy in itself remains unchanged as it transforms from one form to another. [13] Do not assume that “flow” as used here means energy is a fluid. [13] That means atmosphere is possible at least according to thermodynamics an atmosphere of air on planet X is absolutely possible because the air molecules do not have enough thermal energy due to the surface temperature to escape so they would stay close to the planet and produce an atmosphere. [10] If that thermal energy is less then planet X can have an atmosphere at least as far as thermodynamics is concerned. [10]

Normally it would be equal to the final kinetic and the final potential but as we said both of those are zero. [10] This means it has the potential to pick up a lot of speed due to its position relative to the surface of the Earth. [9]

Something important to consider here is that when we calculated the impulse of a single particle along our process to find the pressure, we made one crucial assumption that we assume that each particle individually moved with the same perpendicular speed which is not a very good assumption because the kinetic theory at its basis is supposed to assume that these particles act randomly. [10] Now in truly random motion which, remember, is one of the fundamental assumptions of the kinetic theory the average speed should be isotropic. [10] Alright guys this wraps up our discussion on kinetic theory and more importantly the RMS speed and how it relates to the temperature. [10] Hey guys, in this video we’re going to talk about the kinetic theory and a particular measurement called the RMS speed. [10] We need to figure out what the RMS speed is, how the kinetic theory can tell it to us and why it’s useful. [10]

The mass of each particle remember one of the assumptions the last assumption of the kinetic theory was that the gas particles are all identical. [10] We can easily convert our equation for the pressure of a gas found by the kinetic theory by analysing collisions with the container wall into an equation of state. [10]

The strength of the gravitational attraction between two objects represents the amount of gravitational energy in the field which attracts them towards each other. [17] This in turn restricts the types and hence number and density of virtual particle pairs which can form in the intervening vacuum and can result in a negative energy density. [17] Virtual particles with negative energy can exist for a short period. [17]

Negative energy is a concept used in physics to explain the nature of certain fields, including the gravitational field and various quantum field effects. [17] Negative energy appears in the speculative theory of wormholes, where it is needed to keep the wormhole open. [17] According to the theory of the Dirac sea, developed by Paul Dirac in 1930, the vacuum of space is full of negative energy. [17]

In more speculative theories, negative energy is involved in wormholes which may allow for time travel and warp drives for faster-than-light space travel. [17]

When tiny particles such as electrons, atoms, molecules or ions move at random, they generate energy and heat called thermal energy. [13] What about putting all that stored energy to use? You can attach your rubber band to a simple machine–a wheel and axle–to build a simple rubber band-powered car. [12]
