Question: Which law of motion will be applied to initiate motion of the ball as depicted in the illustration (A) ?

The correct answer is –

The quality of bounce of an object, such as a ball, can be explained by the third law of motion, also known as Newton’s law of action and reaction. This law states that for every action, there is an equal and opposite reaction.

When a ball is dropped or bounces on a surface, the force exerted by the ball on the surface (the action) is equal and opposite to the force exerted by the surface on the ball (the reaction). The quality of bounce depends on how much energy is transferred during the collision between the ball and the surface.

If the ball is dropped on a hard surface, such as concrete, the surface will exert a large force on the ball, causing it to bounce back with a high velocity. On the other hand, if the ball is dropped on a soft surface, such as a foam mattress, the surface will exert a smaller force on the ball, causing it to bounce back with a lower velocity.

Therefore, the quality of bounce can be determined by the interaction between the ball and the surface it bounces on, which is governed by the third law of motion.
