What is inelastic bodies?

However, these energy transformations are constrained by a fundamental principle, the Conservation of Energy principle. One way to state this principle is "Energy can neither be created nor destroyed". Another approach is to say that the total energy of an isolated system remains constant.

Since the principle of elasticity applied to it and hence within the elastic limit any bodies rebound, then they are called perfectly elastic bodies.
