The energy held by a body as a result of its motion is referred to as the body's kinetic energy. A body with kinetic energy can do work on another body.

The kinetic energy of a body of mass " m “ moving with a velocity " v " is given as:

K.E=12mv2

Because of its great velocity, a bullet shot from a gun has a lot of kinetic energy. The bullet's kinetic energy does work on the item it impacts or strikes. As a result of the great kinetic energy held by its velocity, the bullet pierces its target.
