Question

A rubber ball thrown against a wall rebounds back. Why is it so?
Explain it using laws of motion

Answer 1

Answer:

That is because of Newton's third law. The law states that “To every action there is equal and opposite reaction”. This third law gives us the law of conservation of momentum. The ball when it hits the wall exerts a force on the wall and intern the wall exerts force in opposite direction so the ball bounces back.

Answer 2

This is because if the Newton's third law of Motion.

It states that to an every cation there is always equal and opposite reaction.

So, due to this law the rubber ball rebounds back if thrown against a rigid support.

In this case, the force exerted by the ball is slightly more than the force exerted by the wall against its motion due to which it rebounds back but with a lesser velocity.
