n.; pl. Energies [ F. énergie, LL. energia, fr. Gr.&unr_;, fr. &unr_; active; &unr_; in + &unr_; 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. [ 1913 Webster ]

The great energies of nature are known to us only by their effects. Paley. [ 1913 Webster ]

2. Power efficiently and forcibly exerted; vigorous or effectual operation; as, the energy of a magistrate. [ 1913 Webster ]

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. [ 1913 Webster ]

4. (Physics) Capacity for performing work. [ 1913 Webster ]

☞ 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. [ 1913 Webster ]

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

Syn. -- Force; power; potency; vigor; strength; spirit; efficiency; resolution. [ 1913 Webster ]

adj. capable of absorbing energy; as, energy-absorbing bumpers reduce injury and damage in vehicle collisions. [ WordNet 1.5 ]

adj. 1. releasing energy. [ Narrower terms: exothermic (vs. endothermic), exothermal ]
Syn. -- exoergic. [ WordNet 1.5 ]

2. catabolic. [ prenominal ] constructive-metabolic
Syn. -- destructive-metabolic(prenominal). [ WordNet 1.5 ]

adj. 1. anabolic. [ prenominal ]
Syn. -- constructive-metabolic(prenominal). [ WordNet 1.5 ]

n. the branch of particle physics which studies collisions of particles accelerated to such high energy that new fundamental particles are generated in the process. The creation of new particles of very high energy is required to permit the study of the most fundamental relations between forms of matter, so as to understand the fundamental nature of matter. The high energies also reproduce the high-temperature conditions at the earliest phase of the big bang, allowing generation of some data relevant to understanding the nature and evolution of the universe. [ PJC ]

n. Energy derived from nuclear reactions; -- used at present especially of electrical power generated in atomic reactors, but encompassing also fusion energy.
Syn. -- atomic energy, atomic power, nuclear energy, nuclear power. [ WordNet 1.5 ]

n. [ Gr. th^le far + energy. ] Display of force or energy at a distance, or without contact; now more commonly called telekinesis; -- applied to mediumistic phenomena. -- Tel`en*er"gic a. [Webster 1913 Suppl.]
