The energy possessed by a body due its motion is called kinetic energy.
Kinetic Energy Formula is given by
K=1/2 mv2

Where m = mass of the body,
            v is the velocity with which body is moving.

The Kinetic energy is expressed in Kgm2/s2.
Kinetic energy formula is used to calculate the mass, velocity or Kinetic energy of the body if any of the two quantities are given.
