Question

In an elastic collision between two objects do both objects have the same kinetic energy after the collision as before?

Answer 1

Yes , in an elastic collisions between two objects have the same kinetic energy after the collision as before because collision in which both the momentum and kinetic energy is conserved is called as elastic collision.

Answer 2

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
