n (physics) a thermodynamic quantity equivalent to the capacity of a physical system to do work; the units of energy are joules or ergs

Syn|Hypo|Hyper

energy

activation energy, energy of activation

the energy that an atomic system must acquire before a process (such as an emission or reaction) can occur

alternative energy

energy derived from sources that do not use up natural resources or harm the environment

atomic energy, nuclear energy

the energy released by a nuclear reaction

binding energy, separation energy

the energy required to separate particles from a molecule or atom or nucleus; equals the mass defect

chemical energy

that part of the energy in a substance that can be released by a chemical reaction

electrical energy, electricity

energy made available by the flow of electric charge through a conductor

energy level, energy state

a definite stable energy that a physical system can have; used especially of the state of electrons in atoms or molecules

rest energy

the energy equivalent to the mass of a particle at rest in an inertial frame of reference; equal to the rest mass times the square of the speed of light

work

(physics) a manifestation of energy; the transfer of energy from one physical system to another expressed as the product of a force and the distance through which it moves a body in the direction of that force

heat, heat energy

a form of energy that is transferred by a difference in temperature

electromagnetic radiation, electromagnetic wave, nonparticulate radiation

radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge

geothermal energy

energy derived from the heat in the interior of the earth

K.E., kinetic energy

the mechanical energy that a body has by virtue of its motion

heat of dissociation

the heat required for a fluid substance to break up into simpler constituents

heat of formation

the heat evolved or absorbed during the formation of one mole of a substance from its component elements

heat of solution

the heat evolved or absorbed when one mole of a substance is dissolved in a large volume of a solvent

heat of transformation, latent heat

heat absorbed or radiated during a change of phase at a constant temperature and pressure

specific heat

the heat required to raise the temperature of one gram of a substance one degree centigrade

luminous energy

the energy associated with visible light

P.E., potential energy

the mechanical energy that a body has by virtue of its position; stored energy

solar energy, solar power

energy from the sun that is converted into thermal or electrical energy

solar radiation

radiation from the sun

wind generation, wind power

power derived from the wind (as by windmills)

physical phenomenon

a natural phenomenon involving the physical properties of matter and energy
