Newton and volleyball
By JohnV

Newton's First Law:

Part 1 (Inertia): An object at rest will remain at rest unless acted upon by an unbalanced force.

In volleyball: The ball will not go anywhere until someone serves it.

Part 2: (momentum): An
object in motion will remain in motion in a straight line at a constant speed unless acted upon by an unbalanced force.
In volleyball: Once served the ball will travel in an arc due to earth's gravity but will go in one direction only unless someone hits it to change its direction or speed. Then it will continue in the new direction and speed until someone else hits it.
Newton's

Second Law:

Force equals mass times acceleration: f = m X a

In volleyball: The harder you hit the ball the faster it will go it whatever direction you hit it. Also, the ball won’t go over the net unless you hit it hard enough. Also, if you hit the ball too hard it will go out of bounds. Also, a lighter ball will go farther and faster than a heavier ball.

Newton's Third Law:

For every action there is an equal and opposite reaction.

In volleyball: The ball hits your hand just as hard as you hit the ball. To avoid injuring your fingers, hold your hand in the proper position. Also, to make the ball go where you want it to go your must hit it in the proper spot with the proper force.
