Newton's third law of motion describes action and reaction forces. The law states that for every action force, there is an equal and opposite reaction force. Imagine hitting a tennis ball. The racket exerts a force on the ball. This is the action force. The ball exerts an equal and opposite force on the racket. This is the reaction force.

Types of Forces: The boy can grip and move the ball in control because of friction and how the ball is designed to have channels (black grooves) in order to provide a more stable grip. He applies a force downward and the ball falls to the ground with the help of gravity. When the ball is only in the air, only the force of gravity is acting on it.
