# How Is Volleyball Affected by Newton's Law of Motion?

The forces that propel a volleyball forward and over the net behave in the manner explained by all three of Newton's laws of motion. The net force contributes to both the start and finish of the ball's movement.

According to the first law of motion, the ball does not move when no forces are acting on it and the net force is zero. The second part of Newton's first law of motion explains that the ball can remain in motion only as long as it meets no opposing forces. While a serve begins the movement of a volleyball, such factors as gravity and air resistance slow and eventually stop the movement of the ball.

The second law of motion explains the relationship between mass, acceleration and force. In volleyball, a ball has a faster acceleration when it receives a forceful hit. A more massive ball requires a more forceful hit to travel at the same rate of acceleration as a smaller ball.

Newton's third law of motion explains that every force has an opposing force. When a volleyball player forcefully hits a volleyball, the ball exerts an equal force on the player. That force can be the cause of redness or pain from hitting a ball.
