kinetic energy
A bowling ball has kinetic energy when it is moving. When it strikes the pins, some of that energy is passed on to the pins.

## kinetic energy

n.
The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its velocity.

## kinetic energy

n
(General Physics) the energy of motion of a body, equal to the work it would do if it were brought to rest. The translational kinetic energy depends on motion through space, and for a rigid body of constant mass is equal to the product of half the mass times the square of the speed. The rotational kinetic energy depends on rotation about an axis, and for a body of constant moment of inertia is equal to the product of half the moment of inertia times the square of the angular velocity. In relativistic physics kinetic energy is equal to the product of the increase of mass caused by motion times the square of the speed of light. The SI unit is the joule but the electronvolt is often used in atomic physics. Symbols: Ek, K or T Abbreviation: KE

where, [f.sub.tp] is the two-phase friction factor calculated by Churchill equation (Churchill 1977) and is the local cross-sectional void fraction calculated using Zivi kenetic energy model (Zivi 1964):
The kenetic energy of each fragment is proportional to its mass, which in turn is proportional to the cube of the fragment's diameter.
