  1. Energy

    In physics, energy is an indirectly observed quantity which comes in many forms, such as kinetic energy, potential energy, radiant energy, and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects, and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple, intuitive way, although energy can be rigorously defined in theoretical physics. In the words of Richard Feynman, "It is important to realize that in physics today, we have no knowledge what energy is. We do not have a picture that energy comes in little blobs of a definite amount." However, it is clear that energy is always an indispensable prerequisite for performing mechanical work, and the concept has great importance in natural science. The natural basic units in which energy is measured are those used for mechanical work; they always are equivalent to a unit of force multiplied by a unit of length. Other equivalent units for energy are mass units multiplied by velocity units squared.

Chambers 20th Century Dictionary

  1. Energy

    en′ėr-ji, n. power of doing work: power exerted: vigorous operation: strength: (physics) the term, as applied to a material system, used to denote the power of doing work possessed by that system.—adjs. Energet′ic, -al, having or showing energy: active: forcible: effective.—adv. Energet′ically.—n.pl. Energet′ics, the science of the general laws of energy.—adj. Ener′gic, exhibiting energy.—v.t. En′ergise, to give strength or active force to.—v.i. to act with force:—pr.p. en′ergīsing; pa.p. en′ergīsed.Conservation of energy (see Conservation). [Gr. energeiaen, in, ergon, work.]

The Standard Electrical Dictionary

  1. Energy

    The capacity for doing work. It is measured by work units which involve the exercise of force along a path of some length. A foot-pound, centimeter-gram, and centimeter-dyne are units of energy and work. The absolute unit of energy is the erg, a force of one dyne exercised over one centimeter of space. (See Dyne.) The dimensions of energy are   force (M * L / T^2) * space (L) = M * (L^2 / T^2). Energy may be chemical (atomic or molecular), mechanical, electrical, thermal, physical, potential, kinetic, or actual, and other divisions could be formulated.
