Kinetic Energy k</sub>)</strong> </dt>
The energy which a body possesses as a consequence of its motion, defined as one-half the product of its mass m and the square of its speed v, 1/2 mv2. The kinetic energy per unit volume of a fluid parcel is the 1/2 p v2 , where p is the density and v the speed of the parcel. See potential energy.
For relativistic speeds the kinetic energy is given by
