A body which can regain its original shape and size after removing the load (if load cause deformation in body) is called elastic body.

Coefficient of restitution is a thing which will be experienced only when the bodies collide with each other and for a perfect elastic collision we need elastic bodies. Therefore this answer is wrong and e=1 for elastic bodies.

The difference between elastic & perfectly elastic body is if the body is perfectly elastic then the value of e is 1.

Can anyone explain clearly regarding the difference of elastic bodies and elastic collision. I think then it will be clear to differentiate between the coefficients.

The coefficient of restitution (COR) of two colliding objects is a fractional value representing the ratio of speeds after and before an impact, taken along the line of the impact.

Hello @Venu, elastic means "two bodies are tends to elastic collision its coefficient of restitution e=1.
