		Energy, generally and qualitatively speaking, is the property (or the quantity of the property) of changing the state of a system or doing work.
		While kinetic energy is the portion of a system's energy associated with motion, potential energy is the energy of a system associated with the spatial configuration of the system's components and their interaction(s) with each other.
		Internal energy is the kinetic energy associated with the motion of molecules, and the potential energy associated with the rotational, vibrational and electric energy of atoms within molecules.

	Potential Energy, Inertia, and Quantum Coherence
		In the context of special relativity the rest mass of a set of entities is ordinarily defined as the norm of the sum of the energy-momentum vectors of the components.
		The "binding energy" represents the amount of energy that would be required to pull a nucleon away from the nucleus, so the higher the binding energy, the lower the energy level of the configuration.
		Similarly the rest mass of a helium nucleus (two protons bound together by the strong nuclear force) is slightly less than twice the rest mass of an isolated proton.

	ACUFOS - Reflections on Gravity by Martin Gottschall
		In free fall, all rest energy absorbed as the object rises is supplied by its kinetic energy and all rest energy released as the object descends is imparted to the object as kinetic energy.
		Although the rest energy of objects varies in gravity fields, photons and objects in free fall retain the same energy at all values of the gravity potential, giving us a ready-made means for comparing energies from different potentials, and we can therefore say that the total energy is also invariant with respect to gravity potential.
		We know that the energy released by the smaller object adds to its kinetic energy, and we postulate that the energy released by the larger object is fed into or builds up, the slightly intensified gravity field associated with the two objects moving together by the distance "x".

	LUXON THEORY - E=mc 2 (Site not responding. Last check: 2007-10-15)
		During an atom bomb explosion a certain part of the rest mass of the uranium is converted to pure movement mass (the mass of the luxons), or, a part of the rest energy is converted to movement energy (the energy of luxons).
		The whole energy of the luxons increases by the same factor with the velocity of the observer, as the rest energy of tardyons does.
		This is logical, because the rest energy (inertia) of the tardyons, after all, is the energy (inertia) of the inner, trapped luxons.

	Transformation of Excitation Energy between Frames
		When kinetic energy (or potential energy) is added to or removed from a rod, the electron mass and the Bohr radius change as required by the principle of mass-energy conservation.
		The energy that was required to accelerate the mass-equivalent of that excitation energy may appear irrelevant to the moving observer.
		Using the same units, it is clear that the total energy of equation 2.15 (excitation plus the energy required to accelerate the mass-equivalent of the energy of excitation) is equal to the energy of the photon received during the de-excitation by the observer at rest (equation 2.16).

	Rest & Mass-energy in Pluralistic Parcellular Space (Site not responding. Last check: 2007-10-15)
		This zero-point motion of true rest is by definition the state of zero energy, equivalent to the zero-point energy of the quantum vacuum - which we therefore discover to be naturally a component of the quantity "rest mass".
		In other words, rest mass (or rest momentum) is a complex function of positive and negative quantities, respectively like a kinetic energy and a vacuum energy, which latter is in quantum field theory held to reside in an unbounded flux of virtual particles.
		The minima of potential and kinetic energy therefore are co-located in the case of (so-called) free gravitating systems, as with any simple pendulum; but neither curve is in fact interrupted at their mutual intersection, and the zero-point energy of true rest is where the phase of spacetime inverts through a rotation into anti-spacetime.

		In special relativity, however, the energy of a body at rest is determined to be mc2.
		Such a conversion of rest energy to other forms of energy occurs in ordinary chemical reactions, but much larger conversions occur in nuclear reactions.
		This is particularly true in the case of nuclear-fusion reactions that transform hydrogen to helium, in which 0.7 percent of the original rest energy of the hydrogen is converted to other forms of energy.

	The Equivalence of Mass and Energy
		However, as we have seen, this is not the case in relativistic physics, because the energy absorbed by the block of gold contributes to an increase in its rest-mass.
		This is significant because it emphasizes that mass-energy equivalence is not a consequence of a theory of matter; it is instead a direct consequence of changes to the structure of spacetime imposed by SR (see Section 3, Derivations of Mass-Energy Equivalence: History).
		This minority holds that the numerical equivalence of mass and energy is not sufficient to conclude that the two properties are the same.

	The Equivalence of Mass and Energy
		Finally, by saying that mass and energy are the same, these thinkers are suggesting that the denotation of the terms "mass" and "energy" is the same, though they recognize that the connotation of these terms is clearly different.
		Interpretations in the second group establish a connection between the terms "mass" and "energy," which are again treated as terms designating properties, and the two basic constituents in the ontology of physics: matter and fields.
		According to Zahar, energy in pre-relativistic physics occupies a distinct "ontological level" from matter primarily because the former is regarded as dependent on the latter, but not vice versa.

		If such were not the case, then different energies would transform differently, and the moving clock could become aware of its constant velocity by measuring the differing degrees to which energy levels of some items change compared to their rest energies.
		The energy required by any cesium clock atom that has been accelerated out of its calibration reference frame and is now moving uniformly with respect to that frame will be less than that required by a clock atom which remains stationary in our reference frame, as measured in our reference frame.
		Thus it was slowing due to the change in energy associated with this acquired motion--the rest frame of this clock was not the same as the clock to which it was being compared.

		The rest of his career was spent as a university lecturer, first at Liverpool and finally at Bath, in the fields of thermodynamics and fluid mechanics.
		Energy conservation meant that the positive and negative phases of the mixture needed to co-exist in a close balance.
		Used to explore the meaning of "potential energy", the new approach proved that the rest-energy of an object is unaffected by changes of potential as it moves in any field of force, nuclear, electromagnetic, or gravitational.
