We have found that in any impact, except where the coefficient of restitution is unity, some kinetic energy is lost. This missing kinetic energy is converted into other forms of energy and chiefly reappears in the shape of heat. Hence the Principle of Conservation of Energy will not hold good in problems of impact.
