Kinetic energy. See Energy, n. 4.
Wiktionary
n. (context physics English) The energy possessed by an object because of its motion, equal to one half the mass of the body times the square of its velocity.
WordNet
n. the mechanical energy that a body has by virtue of its motion [syn: K.E.]
Wikipedia
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.
In classical mechanics, the kinetic energy of a non-rotating object of mass m traveling at a speed v is . In relativistic mechanics, this is a good approximation only when v is much less than the speed of light.
The standard unit of kinetic energy is the joule.
