power

noun    (Concise Encyclopedia)

In science and engineering, the time rate of doing work or delivering energy. Power (P) can be expressed as the amount of work done (W), or energy transferred, divided by the time interval (t): P = W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short time. Units of power are those of work (or energy) per unit time, such as foot-pounds per minute, joules per second (called watts), or ergs per second. Power can also be expressed as the product of the force (F) applied to move an object and the speed (v) of the object in the direction of the force: P = Fv. See also horsepower.
