Identify each picture as either an inelastic collision or elastic collision

Inelastic collision:

A collision in which there is a loss of Kinetic Energy due to internal friction of the bodies colliding.

Characteristics of an inelastic collision:

In a perfectly elastic collision, the two bodies that collide with each other stick together.

Elastic collision:

A collision in which the kinetic energy of the two bodies, before and after the collision, remains the same.

Characteristics of elastic collision:

In everyday life, no collision is perfectly elastic.

ANSWER:

Given examples:

Reason:

(They lose kinetic energy and come to a stop after the collision.)

Reason:

(a very less amount of kinetic energy is lost)
