Introduction

Do you play basketball? Do you enjoy watching basketball games? Have you ever wondered why the ball bounces?

The ball exerts a downward force when it hits the floor, and exerts an upward force in reaction to gravity when it bounces back. This phenomenon was explained by Sir Isaac Newton, an English scientist. He stated that for every action, there is an equal and opposite reaction. The ball hitting the floor is the action, and the ball bouncing back is the opposite reaction.
