Energy

En"er*gy\, n.; pl. Energies. [F. ['e]nergie, LL. energia, fr. Gr.?, fr. ? active; ? in + ? work. See In, and Work.]

1. Internal or inherent power; capacity of acting, operating, or producing an effect, whether exerted or not; as, men possessing energies may suffer them to lie inactive.

The great energies of nature are known to us only by their effects. --Paley.

2. Power efficiently and forcibly exerted; vigorous or effectual operation; as, the energy of a magistrate.

3. Strength of expression; force of utterance; power to impress the mind and arouse the feelings; life; spirit; -- said of speech, language, words, style; as, a style full of energy.

4. (Physics) Capacity for performing work.

Note: The kinetic energy of a body is the energy it has in virtue of being in motion. It is measured by one half of the product of the mass of each element of the body multiplied by the square of the velocity of the element, relative to some given body or point. The available kinetic energy of a material system unconnected with any other system is that energy which is due to the motions of the parts of the system relative to its center of mass. The potential energy of a body or system is that energy which is not kinetic; -- energy due to configuration. Kinetic energy is sometimes called actual energy. Kinetic energy is exemplified in the vis viva of moving bodies, in heat, electric currents, etc.; potential energy, in a bent spring, or a body suspended a given distance above the earth and acted on by gravity.

Accumulation, Conservation, Correlation, & Degradation of energy, etc. (Physics) See under Accumulation, Conservation, Correlation, etc.

Syn: Force; power; potency; vigor; strength; spirit; efficiency; resolution.

energy

In physics, the ability to do work. Objects can have energy by virtue of their motion (kinetic energy), by virtue of their position (potential energy), or by virtue of their mass (see E = mc2).

Note: The most important property of energy is that it is conserved — that is, the total energy of an isolated system does not change with time. This is known as the law of conservation of energy. Energy can, however, change form; for example, it can be turned into mass and back again into energy.

energy 
1599, from M.Fr. energie, from L.L. energia, from Gk. energeia "activity, operation," from energos "active, working," from en- "at" + ergon "work" (see urge (v.)). Used by Aristotle with a sense of "force of expression;" broader meaning of "power" is first recorded in Eng. 1665. Energize "rouse to activity" is from 1753; energetic of persons, institutions, etc., is from 1796. Energy crisis first attested 1970.

energy   (ěn'ər-jē)  Pronunciation Key 
The capacity or power to do work, such as the capacity to move an object (of a given mass) by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. It is measured by the amount of work done, usually in joules or watts. See also conservation of energy, kinetic energy, potential energy. Compare power, work.
