Explanation:
In every form of collision the momentum is conserved and it is the same before and after the collision, but in perfectly elastic collision, there is no loss of kinetic energy in the collision. In an inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision. Any macroscopic collision between objects will convert some of the kinetic energy into internal energy and other forms of energy.
