In serving and spiking, the player is make a forceful
connection with an object (the volleyball), to make it travel
across the net. Work also occurs from passing and setting,
because the ball is moving away with the work done on the ball.
The player is exerting enough force on the ball, to have it move
away.
Volleyball would not be a functioning sport if zero work
was involved. Work in physics is when a force moves an object.
Every single play in volleyball involves work, whether it be
setting, passing, spiking, or serving. I think of serving and
spiking as having the most force and the most representation of
work in a volleyball game.
The final aspect of volleyball that gravity shows up in
is spiking or attacking the ball. A spike already has a
downward force created by the player, and gravity only helps the
ball move closer to the floor. In this aspect, gravity
helps in your offensive favor.
Gravity also shows up in passing/setting. A
player hits the ball with their arms, and must exert enough
force so that another player can reach the ball before the force
of gravity forces the ball to the ground. Gravity prevails
if the pass does not have enough force to make it to the person,
and gravity is bested if the player exerts the perfect amount of
force.
Gravity is the force of attraction between an object
and the earth. Every play in volleyball includes the
forces of gravity. To start a point, a player serves the
ball over the net. Gravity is seen here when the player first
throws the ball. The ball obviously does not stay in the air, it
instead falls back down so that the player can serve the ball.
