The interatomic force is equal to the negative gradient of the corresponding potential energy function. [1] The work done by a conservative force equals the NEGATIVE of the change in the potential energy associated with that force. [1] In that case, $U$ denotes the gravitational potential energy of a configuration of two (or more) objects interacting gravitationally. $\Phi$ denotes the gravitational potential of one object. [2] It assigns a number $\phi_g$ (or $U$ or whatever) to every point of the space, so that $m\cdot \phi_g$ is the real potential energy. [2] If we are working in the two-body case, one (usually more massive) body with mass $M$ and one (usually smaller, test-body) with mass $m$, then once I figure out the gravitational field of: $\Phi-GM/r$, I can easily obtain the gravitational potential energy of the two bodies together by: $Um\Phi -GMm/r$. [2] Potential Energy is the energy which arises due to the difference in Potential. [3] Potential energy is the amount of energy it acquires due to that Potential difference. [3]

If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount. [4] The amount of gravitational potential energy possessed by an elevated object is equal to the work done against gravity in lifting it. [5] An object at a certain height above the Moon's surface has less gravitational potential energy than at the same height above the Earth's surface because the Moon's gravity is weaker. [4] This is called gravitational potential energy because its energy the object gains from its vertical position. [6] The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam. [4]

Chemical potential energy, such as the energy stored in fossil fuels, is the work of the Coulomb force during rearrangement of mutual positions of electrons and nuclei in atoms and molecules. [5] This work is stored in the force field, which is said to be stored as potential energy. [5] The force field is defined by this potential function, also called potential energy. [5] The function U ( x ) is called the potential energy associated with the applied force. [5] The function U ( x ) 1/2 kx 2 is called the potential energy of a linear spring. [5] The function U ( s ) mgh is called the potential energy of a near earth gravity field. [5] While all the working fluid in a steam engine may have higher energy due to gravity while sitting on top of Mount Everest than it would at the bottom of the Mariana Trench, the gravitational potential energy term in the formula for the internal energy would usually be ignored because changes in gravitational potential within the engine during operation would be negligible. [7] Note that "height" in the common sense of the term cannot be used for gravitational potential energy calculations when gravity is not assumed to be a constant. [4] Roller coasters are an entertaining way to utilize potential energy - chains are used to move a car up an incline (building up gravitational potential energy), to then have that energy converted into kinetic energy as it falls. [5] Gravitational potential energy is also used to power clocks in which falling weights operate the mechanism. [5] As with all potential energies, only differences in gravitational potential energy matter for most physical purposes, and the choice of zero point is arbitrary. [5] The singularity at r0 in the formula for gravitational potential energy means that the only other apparently reasonable alternative choice of convention, with U0 for r0, would result in potential energy being positive, but infinitely large for all nonzero values of r, and would make calculations involving sums or differences of potential energies beyond what is possible with the real number system. [5] The work of a force acting on a moving body yields a difference in potential energy when the integration of the work is path independent. [5] Potential energy is associated with a set of forces that act on a body in a way that depends only on the body's position in space. [5] Potential energy is often associated with restoring forces such as a spring or the force of gravity. [5] Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth's gravity. [4] The work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy ; work of the strong nuclear force or weak nuclear force acting on the baryon charge is called nuclear potential energy; work of intermolecular forces is called intermolecular potential energy. [5] In case the electric charge of an object can be assumed to be at rest, it has potential energy due to its position relative to other charged objects. [5] In physics, potential energy is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system. [5] The more formal definition is that potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position. [5] The more massive an object is, the greater its gravitational potential energy. [6] Over large variations in distance, the approximation that g is constant is no longer valid, and we have to use calculus and the general mathematical definition of work to determine gravitational potential energy. [5] Trebuchet : A trebuchet uses the gravitational potential energy of the counterweight to throw projectiles over long distances. [4] Gravitational potential energy has a number of practical uses, notably the generation of hydroelectricity. [5] Another practical use is utilizing gravitational potential energy to descend (perhaps coast) downhill in transportation such as the descent of an automobile, truck, railroad train, bicycle, airplane, or fluid in a pipeline. [5] At times when surplus electricity is not required (and so is comparatively cheap), water is pumped up to the higher lake, thus converting the electrical energy (running the pump) to gravitational potential energy. [5] At times of peak demand for electricity, the water flows back down through electrical generator turbines, converting the potential energy into kinetic energy and then back into electricity. (The process is not completely efficient and some of the original energy from the surplus electricity is in fact lost to friction.) [5] Thermal energy usually has two components: the kinetic energy of random motions of particles and the potential energy of their mutual positions. [5] The potential energy of the system of bodies as such is the negative of the energy needed to separate the bodies from each other to infinity, while the gravitational binding energy is the energy needed to separate all particles from each other to infinity. [5] This potential energy is more strongly negative than the total potential energy of the system of bodies as such since it also includes the negative gravitational binding energy of each body. [5] A book lying on a table has less gravitational potential energy than the same book on top of a taller cupboard, and less gravitational potential energy than a heavier book lying on the same table. [4] The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in. [4] If you lift a mass m by h meters, its potential energy will be mgh, where g is the acceleration due to gravity. [6] If the book falls off the table, this potential energy goes to accelerate the mass of the book and is converted into kinetic energy. [4] An object held in a person's hand has potential energy, which turns to kinetic energy -- the energy of motion -- when the person lets it go, and it drops to the ground. [8] It is called potential energy because it has the potential to be converted into other forms of energy, such as kinetic energy. [6] In some cases the Kinetic energy obtained from potential energy of descent may be used to start ascending the next grade such as what happens when a road is undulating and has frequent dips. [5] This is contrast to external energy which is a function of the sample with respect to the outside environment (e.g. kinetic energy if the sample is moving or potential energy if the sample is at a height from the ground etc). [9] The potential energy is a function of the state a system is in, and is defined relative to that for a particular state. [5] Typically the potential energy of a system depends on the relative positions of its components only, so the reference state can also be expressed in terms of relative positions. [5] One gram of water at zero °Celsius compared with one gram of copper at zero °Celsius do NOT have the same internal energy because even though their kinetic energies are equal, water has a much higher potential energy causing its internal energy to be much greater than the copper's internal energy. [9] Chemical Potential Energy; Burn a sample of the substance in oxygen, use the heat given off to warm a bit of water and watch the temperature rise. [10] Potential energy may also refer other forms of stored energy, such as energy from net electrical charge, chemical bonds, or internal stresses. [6] Chemical bonds may also have potential energy, as electrons can move closer or further away from atoms. [6] For example in elastic potential energy, stretching an elastic material forces the atoms very slightly further apart. [5] There are various types of potential energy, each associated with a particular type of force. [5] Weak nuclear forces provide the potential energy for certain kinds of radioactive decay, such as beta decay. [5] One may think of potential energy as being derived from force or think of force as being derived from potential energy (though the latter approach requires a definition of energy that is independent from force which does not currently exist). [5] The needle of a compass has the lowest magnetic potential energy when it is aligned with the north and south poles of the Earth's magnetic field. [5] The magnetic potential energy of the needle is highest when it is perpendicular to the Earth's magnetic field. [5] There is geometric justification in setting ? o as the locus of zero potential energy for the mass of S'. [5] Elastic potential energy is the potential energy of an elastic object (for example a bow or a catapult) that is deformed under tension or compression (or stressed in formal terminology). [5] This is elastic potential energy, which results from stretching or compressing an object. [6] When the string is released, the potential energy in the bow limbs is transferred back through the string to become kinetic energy in the arrow as it takes flight. [5] The electrostatic potential energy is the energy of an electrically charged particle (at rest) in an electric field. [5] Nuclear potential energy is the potential energy of the particles inside an atomic nucleus. [5] There are two main types of this kind of potential energy: electrostatic potential energy, electrodynamic potential energy (also sometimes called magnetic potential energy). [5] For the computation of the potential energy we can integrate the gravitational force, whose magnitude is given by Newton's law of gravitation, with respect to the distance r between the two bodies. [5] Two magnets will have potential energy in relation to each other and the distance between them, but this also depends on their orientation. [5] Potential energy is usually denoted by the capital letter U in equations or sometimes by PE. [6] In an electrical system, potential energy is expressed as voltage. [6] More specifically, every conservative force gives rise to potential energy. [5]

The associated potential is the gravitational potential, often denoted by \phi or V, corresponding to the energy per unit mass as a function of position. [5] A thermodynamic potential (in fact, rather energy 1, 2 than potential) is a scalar quantity used to represent the thermodynamic state of a system. [7] The thermodynamic potentials can also be used to estimate the total amount of energy available from a thermodynamic system under the appropriate constraint. [7] Expressions for all other thermodynamic energy potentials are derivable via Legendre transforms from an expression for U. [7] It is the energy of configuration of a given system of conservative forces (that is why it is called potential) and only has meaning with respect to a defined set of references (or data). [7] These five common potentials are all energy potentials, but there are also entropy potentials. [7] The geometric displacement of the potential well from the c.o.m. in S' indicates a force of attraction (-?). ransformed momentum (17) produces equivalent values; therefore, the kinetic energy derived from this relationship is likewise equivalent to the deri. thy, having the lowest mass per nucleon (highest mass defect), and greatest magnetic ability in the Periodic Table. [5] The internal energy of a system is identified with the random, disordered motion of molecules; the total (internal) energy in a system includes potential and kinetic energy. [9] One main thermodynamic potential that has a physical interpretation is the internal energy U. [7]

It is often denoted by the symbol F, but the use of A is preferred by IUPAC, 4 ISO and IEC. 5 N i is the number of particles of type i in the system and i is the chemical potential for an i -type particle. [7] When comparing substances, it's often more instructive to speak of their specific energy or specific work or gravimetric energy density or volumetric energy density (energy per mass) symbol e or w. [10] The SI unit for measuring work and energy is the joule (symbol J). [5]

The negative of the work done by the electric force is defined as the change in electric potential energy, U, of the body. [11] Again, note that the work done by the electric field is positive and the negative charge will lose electric potential energy and gain kinetic energy as it moves against the field. [11] Electrical potential V(t) of a position in the electrical field is such that, electric potential energy is required to place a particle of charge q at that position, would be the product of charge of the particle q and the potential of that position V(t). [12] Which says Voltage is the difference in electric potential energy per unit charge between two points. [12] Just as mass in a gravitational field has some potential energy, so does a charge in an electric field. [11] When a charged particle moves in an electric field, if its electric potential energy decreases, its kinetic energy will increase. [11] When a chemical bond forms (an exothermic process with Δ E < 0), the decrease in potential energy is accompanied by an increase in the kinetic energy (embodied in the momentum of the bonding electrons), but the magnitude of the latter change is only half as much, so the change in potential energy always dominates. [13] This chapter covers the following topics: Definition of a chemical bond and of a molecule, structural formulas, visualization of complex structures, potential energy curves, bond energies, bond lengths, infrared absorption spectra, greenhouse gas warmng. [13] The internuclear distance at which the potential energy minimum occurs defines the bond length. [13] Attractive forces operate between all atoms, but unless the potential energy minimum is at least of the order of RT, the two atoms will not be able to withstand the disruptive influence of thermal energy long enough to result in an identifiable molecule. [13] The bond energy is the amount of work that must be done to pull two atoms completely apart; in other words, it is the same as the depth of the well in the potential energy curve shown above. [13] Potential energy and kinetic energy Quantum theory tells us that an electron in an atom possesses kinetic energy K as well as potential energy P, so the total energy E is always the sum of the two: E P + K. [13] It will, therefore, lose electric potential energy and gain kinetic energy. [11] Potential energy (PE) Mass(M) X Gravitational acceleration (g) X Altitude (h). [14] In other words: a large bolder x it sitting on the top of a mountain x the gravitational pull has a lot of potential energy to be realized when it becomes dislodged and rolls down the Mountain. [15] Looking for the shorthand of Gravitational Potential Energy ? This page is about the various possible meanings of the acronym, abbreviation, shorthand or slang term: Gravitational Potential Energy. [16] Potential energy can be defined as the energy possessed by the body by virtue of its configuration or position. [14] These are depicted by the horizontal lines in the potential energy curve shown here. [13] For the moment you only need to know that in any stable structure, the potential energy of its atoms is lower than that of the individual isolated atoms. [13] The bond energy Δ E has half the magnitude of the fall in potential energy. [13] Sketch out a potential energy curve for a typical diatomic molecule, and show how it illustrates the bond energy and bond length. [13]

Find an integral expression for the gravitational potential $\Phi (x,y)$ for a general point in the (x,z) plane. [2] Generally you obtain the gravitational potential $\Phi$ by breaking down the gravitating objects into small (differential) chunks, and then adding up each chunk's contribution to the overall gravitational potential. [2] The difference between them, is that $U$ requires (at least) two objects in order to be defined, while $\Phi$ is the potential of one object. [2] Each object in the universe tries to attain low POTENTIAL state. [3]

#vecF-vecgradU# where #F# is the Force and #U# is the potential. [3] I have a set of problems about "gravitational potential $\Phi$." [2] That's why electric charges (+ve or -ve) move from region of high potential to low potential. [3] Not the answer you're looking for? Browse other questions tagged gravity terminology potential potential-energy notation or ask your own question. [2] Electrons tend to be near the nucleus of the atom #ie# in the region of least potential. [3] Both the gravitational field and the gravitational potential are FIELDS. [2]

The force applied is the negative of the conservative force, so that net force on the body is 0 and it does not gain kinetic energy. [1] You can use any symbol as long as you are consistent and you se tit clear at the beginning. [2]

Because the potential U defines a force F at every point x in space, the set of forces is called a force field. [5] There is a function U ( x ), called a "potential," that can be evaluated at the two points x (t 1 ) and x (t 2 ) to obtain the work over any trajectory between these two points. [5] If the work done moving along a path which starts and ends in the same location is zero, then the force is said to be conservative and it is possible to define a numerical value of potential associated with every point in space. [5] If the work of forces of this type acting on a body that moves from a start to an end position is defined only by these two positions and does not depend on the trajectory of the body between the two, then there is a function known as a potential that can be evaluated at the two positions to determine this work. [5] Examples of work that can be computed from potential functions are gravity and spring forces. [5] The action of stretching the spring or lifting the mass is performed by an external force that works against the force field of the potential. [5] A force field can be re-obtained by taking the negative of the vector gradient of the potential field. [5] In thermodynamics, external forces, such as gravity, are typically disregarded when formulating expressions for potentials. [7] Examples of forces that have potential energies are gravity and spring forces. [5] On the converse, if a thermodynamic potential is not given as a function of its natural variables, it will not, in general, yield all of the thermodynamic properties of the system. [7] This yields expressions for various thermodynamic parameters in terms of the derivatives of the potentials with respect to their natural variables. [7] There will be one fundamental equation for each thermodynamic potential, resulting in a total of 2 D fundamental equations. [7] All thermodynamic information about the system will be known, and that the fundamental equations for any other potential can be found, along with the corresponding equations of state. [7] The definitions of the thermodynamic potentials may be differentiated and, along with the first and second laws of thermodynamics, a set of differential equations known as the fundamental equations follow. 9 (Actually they are all expressions of the same fundamental thermodynamic relation, but are expressed in different variables.) [7] The chemical reactions usually take place under some constraints such as constant pressure and temperature, or constant entropy and volume, and when this is true, there is a corresponding thermodynamic potential that comes into play. [7] Thermodynamic potentials are very useful when calculating the equilibrium results of a chemical reaction, or when measuring the properties of materials in a chemical reaction. [7] The similar term chemical potential is used to indicate the potential of a substance to undergo a change of configuration, be it in the form of a chemical reaction, spatial transport, particle exchange with a reservoir, etc. [5] The thermodynamic square can be used as a tool to recall and derive some of the potentials. [7] Similar equations can be developed for all of the other thermodynamic potentials of the system. [7] In all, there will be D equations for each potential, resulting in a total of D 2 D equations of state. [7] From these we get the Maxwell relations. 3 11 There will be ( D ? 1) / 2 of them for each potential giving a total of D ( D ? 1) / 2 equations in all. [7]

Note that the infinitesimals on the right-hand side of each of the above equations are of the natural variables of the potential on the left-hand side. [7] Again, define x i and y i to be conjugate pairs, and the y i to be the natural variables of some potential. [7] Notice that the set of natural variables for the above four potentials are formed from every combination of the T - S and P - V variables, excluding any pairs of conjugate variables. [7]

With friction, the route taken does affect the amount of work done, and it makes little sense to define a potential associated with friction. [5] This gives a mathematical justification of the fact that all conservative forces are gradients of a potential field. [5] If it did then it would be pointless to define a potential at each point in space. [5] If there are D dimensions to the thermodynamic space, then there are 2 D unique thermodynamic potentials. [7] The concept of thermodynamic potentials was introduced by Pierre Duhem in 1886. [7] For the most simple case, a single phase ideal gas, there will be three dimensions, yielding eight thermodynamic potentials. [7] As in the above sections, this process can be carried out on all of the other thermodynamic potentials. [7]

? denotes the change in the potential and at equilibrium the change will be zero. [7] If the D equations of state for a particular potential are known, then the fundamental equation for that potential can be determined. [7]

This reference state is not always a real state, it may also be a limit, such as with the distances between all bodies tending to infinity, provided that the energy involved in tending to that limit is finite, such as in the case of inverse-square law forces. [5] Often interactions are described in terms of energy rather than force. [5]

Considering the system of bodies as the combined set of small particles the bodies consist of, and applying the previous on the particle level we get the negative gravitational binding energy. [5] Since physicists abhor infinities in their calculations, and r is always non-zero in practice, the choice of U0 at infinity is by far the more preferable choice, even if the idea of negative energy in a gravity well appears to be peculiar at first. [5]

This follows from the first and second laws of thermodynamics and is called the principle of minimum energy. [7] Gibbs energy 2 ( G ) is the capacity to do non-mechanical work. [7] From these meanings (which actually apply in specific conditions, e.g. constant pressure, temperature, etc), we can say that ? U is the energy added to the system, ? F is the total work done on it, ? G is the non-mechanical work done on it, and ? H is the sum of non-mechanical work done on the system and the heat given to it. [7] Helmholtz energy 1 ( F ) is the capacity to do mechanical plus non-mechanical work. [7]

The energy that exists in a body as a result of its position or condition rather than of its motion. [8] Green plants transform solar energy to chemical energy through the process known as photosynthesis, and electrical energy can be converted to chemical energy through electrochemical reactions. [5] Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction. [5] When a fuel is burned the chemical energy is converted to heat, same is the case with digestion of food metabolized in a biological organism. [5]

This energy will generally be non-zero if there is another electrically charged object nearby. [5] Whether we feel cursed or blessed, our coming upon the unique life/ energy that is U.G. can change our life forever. [5] By the second law of thermodynamics, we can express the internal energy change in terms of state functions and their differentials. [7] An isolated system cannot exchange heat or work with its surroundings making the change in internal energy equal to zero. [9] Internal energy ( U ) is the capacity to do work plus the capacity to release heat. [7]

Levine, Ira N. "Thermodynamic internal energy of an ideal gas of rigid rotors." [9] Again, define x i and y i to be conjugate pairs, and the y i to be the natural variables of the internal energy. [7]

At distances of several atomic diameters attractive forces dominate, whereas at very close approaches the force is repulsive, causing the energy to rise. [13] In order to jump to a higher state, the molecule must absorb a photon whose energy is equal to the distance between the two states. [13] The terms energy level and energy state are often used loosely to mean quantum state. [18] It can also be used to represent dynamic pressure, fusion energy gain factor, heat, mementum transfer and volumetric flow rate. [19]

For ordinary chemical bonds, the energy differences beween these natural vibrational frequencies correspond to those of infrared light. [13] This is almost, but not quite the same as the bond dissociation energy actually required to break the chemical bond; the difference is the very small zero-point energy. [13]

It is important to bear in mind that the exact properties of a specific kind of bond will be determined in part by the nature of the other bonds in the molecule; thus the energy and length of the CH bond will be somewhat dependent on what other atoms are connected to the carbon atom. [13] These vibrations are initiated by the thermal energy of the surroundings; chemically-bonded atoms are never at rest at temperatures above absolute zero. [13] At large distances the energy is zero, meaning no interaction. [13] The energy of a system of two atoms depends on the distance between them. [13]

Introductory courses usually review the various fields to show how concepts of matter, energy, power, and time interconnect. [19] Applied Physics is generally called engineering.The branch of science concerned with the nature and properties ofmatter and energy. [19]

The charge is forced to move from a low potential point to a high potential point and the work done by the external force is negative. [11] When a point charge is the source of the field, then any two points that are the same distance from the point charge (points A and C in Figure 2) will be at the same potential. [11] A point in this space near the source of the field (i.e., near the point charge), and another point far from the source of the field are at different potentials. [11] In Fig. 2, points A and B are at different potentials due to the electric field of the positive charge. [11] The electric field points from high to low electrical potential (voltage). [11] In general, the zero point is at infinity; however, often in circuits, the zero point for the potential is the ground or a conductor that is directly connected to the ground. [11] Recall that on the earth, the gravitational field points from high to low gravitational potential. [11]

You can make the scatter plot for all of your equipotentials by placing the x coordinate of each measurement in column 1 and the associated y measurements for each surface in a different column for each of the values of the potential measured. [11] Once you have entered the equipotentials, you can now sketch the E-field lines corresponding to these potential surfaces using the rules governing these lines described in the lab write up. [11] Enter this data into a new spreadsheet and then make a scatter plot of the potential surfaces as done above. (Note: You should repeat the process that you used in the previous section to map these surfaces.) [11]

Electrical potential and electrical field vector, both characterize the same thing that is space of electrical field. [12] The SI unit of electrical potential is Volt after name of Italian physicist Alessandro Volta (1745 - 1827). [12]

It is revealed by God, as he takes that potential and turns it into something powerful for the good of His kingdom work on earth. [15] That?s because God works best, and Christian Potential is at its best, when U means not little old you. [15] That?s Satan?s scheme to rob the church and the individual members of the church from the powerful potential that God desires us to have when we are together and serve as the Body of Christ. [15] This tells us that electric potential decreases in the direction of the electric field lines. [11] This weekend I want to take the scientific mathematical formula for potential, and use those letters for an acronym to define Christian Potential. [15] Enter this data into a spreadsheet and then make a scatter plot of the potential surfaces as done above. (Once again, use the procedure from the previous mapping exercises to find the equipotential surfaces for this configuration.) [11]

There are an infinite number of points--all lying on the same sphere--that are at the same distance, all of which are at the same potential. [11]

Voltage is not exactly potential; it is the measure of electric potential difference of two points. [12] Voltmeter is used to measure the potential difference between two points. [12] In two dimensions--say, the equatorial plane of the sphere--the circle (equator) where the sphere intersects the plane is an equipotential line; the potential difference between any two points on this line is zero. [11]

A voltage which is a measure of electric potential difference, is the cause of electrical current to flow in a closed circuit. [12] Another physical quantity is there which is much easier to measure and also used to characterise an electric field, and this quantity is known as electric potential difference. [12]

The symbol Q is used in physics to represent electric charge. [19] can be used for the symbol for distance moved as well as the symbol for wavelength. [19] The SI unit is the joule but the electronvolt is often used in atomic physics., (Symbol) Ek, K, T (Abbrev.) [18] They are also emotionally motivating, and are commonly used to make presentations more effective and appealing to a wide ranging audience. Symbols make it easier to instantly recognize what we should do in traffic. [19] The symbol 'u' is often used in place of the prefix 'micro-' in math and physics. [19] The chemical symbol of carbon is C. Two physical properties are (1) solid at room temperature and (2) high melting point. [19] Chemists talk about bonds all the time, and draw pictures of them as lines joining atom symbols. [13] Common symbols include flags of nations, crosses on churches, x - railroad crossing sign. Symbols are appealing to use because they are often universal, crossing the language barriers between people. [19] Sometimes it's hard to remember all of the symbols so sometimes they use colours. [19] By convention we use the lower-case Greek letter, rho ( ρ.), for the density symbol in physics. [19]

Making the scatter plot this way results in each of the equipotential surfaces having a different symbol in the plot making it easy to connect-the-dots and sketch the equipotential surfaces. [11]

In thermodynamics, it is used to represent internal energy. [19] In relativistic physics kinetic energy is equal to the product of the increase of mass caused by motion times the square of the speed of light. [18] The translational kinetic energy depends on motion through space, and for a rigid body of constant mass is equal to the product of half the mass times the square of the speed. [18] The rotational kinetic energy depends on rotation about an axis, and for a body of constant moment of inertia is equal to the product of half the moment of inertia times the square of the angular velocity. [18]

For this reason, the values listed in tables of bond energy and bond length are usually averages taken over a variety of compounds that contain a specific atom pair. [13]
