TAKE THE QUIZ TO FIND OUT 1575–85; <Late Latin energīa<Greek enérgeia activity, equivalent to energe- (stem of energeîn to be active; see en-2, work) + -ia-y3 hy·per·en·er·gy, nounself-en·er·gy, noun energid, energism, energize, energizer, energumen, energy, energy audit, energy band, energy bar, energy conversion, energy crop Dictionary.com Unabridged Based on the Random House Unabridged Dictionary, © Random House, Inc. 2022 Energy refers to available power or motivation to move, as in Jada found that getting enough sleep each night gave her the energy to live each day. Energy also refers to power that is used with exertion or force, as in Monique brought energy to the team, leading them to win more games. In physics, energy is the power or heat that is created when something moves, is burned, or is exerted. It is typically represented in two forms: potential and kinetic energy. Potential energy is power that is stored in something as it sits still or is unburned. For example, coal contains a large amount of potential energy that is released when the coal is burned. As the coal burns, that potential energy becomes kinetic energy, energy related to the particles in the system. Energy is a common word with several other senses related to power or motivation. Example: Darryl found out the hard way that cell phone batteries lose their energy in the cold. The first records of the term energy come from the late 1500s. It ultimately comes from the Greek term energeîn, meaning “to be active.” Activity can come in many forms, but almost all burn energy. Potential and kinetic energy can be applied to humans, too. As you eat and sleep, you build up potential energy, and as you physically move, think, breathe, or perform any physical action, that energy is used kinetically. When you’re tired, you might say you’re low on energy. And when you decide to put your energies into your art, you are spending more time doing your art and, as a result, spending more of your energy on it. Energy is a common word used both in the scientific sense and in other senses, particularly those related to the power we or our devices have or don’t have.

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.

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.
