There is an interesting relationship between the final velocity of the object. From Newton's Second Law of Motion,  Also if we set  as the final velocity and  as the initial velocity there exist a relationship:
 Since,  if we apply it to,  the result is,  Here, the quantity  is call the kinetic energy, K and is dependent on the velocity and the mass of the moving object.Since the work done is equal to the final kinetic energy minus the initial kinetic energy, the total work and be described as the change of the object's kinetic energy. 
In most of the cases the change in a form of energy is associated with the tranformation of that energy into another form of energy.
 The work done by the force applied on the object is equal to mgh. Since motion is in the opposite direction to that of the force of gravity, the work done by gravity in this case is -mgh. The work mgh has been preserved as t he gravitational potential energy, U. In the like manner, the transformation of energy is presented as work.
 Therefore,
