This lack of conservation means that the forces between colliding objects may remove or add internal kinetic energy. Work done by internal forces may change the forms of energy within a system. For inelastic collisions, such as when colliding objects stick together, this internal work may transform some internal kinetic energy into heat transfer.

A perfectly elastic collision is one in which none of the initial kinetic energy is converted into heat or deformation. A perfectly inelastic collision is one in which all of the initial kinetic energy is converted into heat and deformation.
