COLLISIONS - ELASTIC
In a collision, if the colliding objects deform and then spring back to their original shapes, the collision is said to be ELASTIC. Elastic collisions are typically characterized by objects hitting and bouncing from one another.A glass bead bouncing off a steel plate is highly elastic. Putty hitting the same steel plate deforms and does not return to its original shape (it also doesn't bounce). This would be called an INELASTIC COLLISION.
