Serving
In
volleyball when serving one must stand behind the end line, which is 30
feet from the net. The net measures 90 inches, or 96 inches for men,
from the ground. The goal is to get the ball across the net with as
little time as possible so that the other team has less time to react
and handle the ball. Traditionally serving has been done from the floor
where the server has to create a parabolic motion path for the ball to
travel so that it will clear the net and then land within the
boundaries of the court.
In modern volleyball the game has
progressed to more of a vertical game, with jump serving. The
advantages that jump serving gives have to do with the physics of
projectile motion. The angle in which the server’s initial velocity has
to start from is smaller, because as the height increases the slope of
the parabola in the motion of the ball decreases. As the height of
contact increases the path that the ball follows becomes line like as
it crosses the net and if the contact height is high enough and the
ball is contacted correctly the ball will have a downward path similar
to that of a triangle.
