## Motion in volleyballBy phoebe Rutkowski

First, Newton's laws of motion. The first law of motion states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

The second states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

The third law states that for every action, there is an equal and opposite reaction.

An example of Newton's first law in volleyball is when the ball is traveling over the net. The ball will continue to travel until it is acted upon by another player or the floor. The ball will also be slowed down slightly by fluid friction/ air resistance.

An example of the second law of motion in volleyball is when the ball is served. The force and momentum of the setter's hand is transferred to the ball, which makes the ball accelerate from zero and soar over the net.

An example of the third and final law of motion in volleyball is when it is bumped into a volley. the force of the ball landing on the player's fist is met with the momentum of the player swinging upward and the ball's original path is canceled, instead flying in the direction the player hit it.

Force formula: Force= mass x acceleration (f= ma)

Momentum formula: momentum = mass x velocity (p= mv)
