Question

Erica throws a tennis ball against a wall, and it bounces back. Which force is responsible for sending the ball back to Erica?

Answer 1

Probably the elastic force as it compresses and then expands

Answer 2

Reaction force

Step-by-step explanation:

The force with which the ball is thrown towards the wall is the action force.

The ball bounces back in the opposite direction, with an equal force. So this bouncing back in the reverse direction is called the reaction force.

The 3rd law of motion, as given by Newton states that whenever there is an action, an equal but opposite reaction occurs.

Suppose the reaction force is not equal but less, the ball will drop down. Since the ball strikes against the wall, the force with which it is thrown cannot get stronger than the action force.
