What is elastic collision?

Collisions in which the total kinetic energy remains constant are called elastic collision.

What is inelastic collision?

Collisions in which the total Kinetic energy is less after the collision than it was before, the collision are called inelastic.

Before the collision, the stick is moving towards the ball at a high speed. After the collision, the stick stops moving. It transfers some of its kinetic energy to the cue ball, which rolls forward.
