Net work on an object causes a change in the kinetic energy. The work done in a body due to a force is equal to the change in its kinetic energy.
i.e. Work done = Change in Kinetic Energy
Consider a body of mass M, moving with a initial velocity u when a constant force F is acts on it. Let final velocity of the body becomes v after covering a distance d in a direction of force. Then, work done by the force is given by
