Elastic vs. Inelastic Collision

The difference between Elastic Collision and Inelastic Collision is that when elastic collision happens the two objects will bounce off each other and when inelastic collision happens the objects sill stick together.  An example of inelastic collision is when you roll a marble towards another marble because the marbles are going to keep moving together and at the same speed. And an example of elastic collision is when something small tries to push something big.
