Two bouncy balls colliding with each other is an example of what type of collision?

Elastic collision

Explanation:

The interaction of two particles is called collision. There are two types of collision i.e. elastic collision and inelastic collision.

Two bouncy balls colliding with each other is an example of elastic collision. In this type of collision the momentum and kinetic energy of the bodies remains constant i.e.

and

Where

m₁ and m₂ are masses of two balls A and B

u₁ and u₂ are initial velocities of ball A and B

v₁ and v₂ are final velocities of ball A and B
