Question

Stephanie is in volleyball practices and she notices something interesting about the
effect that spiking the ball has on her hand. She notices that the harder she hits the
ball, the more that her hand hurts afterward. Which Newton's Law explains why this
happens?

Answer 1

Newton’s Second law

Answer 2

The Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.

Newton's third law of motion, states that, action and reaction are equal and opposite.

The force exerted on the ball when Stephanie spikes is equal to the reaction the ball exerts back on Stephanie. As the force Stephanie applied increases, the reaction she receive from the ball increases as well and the more pain she will feel.

Thus, we can conclude that, the Newton's law that explains the reason for the pain experienced by Stephanie when she spikes the ball is Newton's third law of motion.
