Speed
Speed Is how fast an object is moving.
Player: The player uses speed to move around on the volleyball court. The player will constantly be changing their speed to either slow down or speed up. Also another occasion when players use speed is when they swing their arm to hit the ball. They will swing back their arm, but must control their speed of the arm because this will determine the force acted on the ball. If the force is too much then it will go out of bounds, but if its not enough force then it will not go over the net.
Volleyball: The volleyball also has speed, since its an object and moves throughout the game. Although, when it slow downs and goes faster, it has to do more with acceleration and velocity than speed.

Acceleration
Acceleration is an increase in velocity and this can be found in volleyball all the time.
For example, in a game when a volleyball player serves the ball, it's gone over the net, and is falls to the ground. As gravity pulls the ball to the ground, it accelerates. Although, the ball will come back at the player and she has to gently hit the ball over the net. Now her opponent sends a hard spike back at her team, now that's another example of acceleration. The ball's velocity increased when spiked back over the net, by the opponent, therefore it accelerated. Another example, is the player always has to accelerate towards the ball, to hit it over the net. This amount of acceleration towards the ball will determine if she reaches on time to avoid it form hitting the ground and costing her team a point. The science is that she has to quickly either increase her velocity towards net, to her right, or to her left.

Velocity
Velocity is the speed of an object in a particular direction.
I think the best example of velocity during volleyball is a spike, because every part of the spike is dependent upon velocity. Starting from the approach, to the arm swing, and even the follow through. First the hitter must gain velocity by taking an approach, usually about three step advance toward the net. Then the player swings her arms in an attempt to gain momentum for the jump. Once in the air, she pulls her arm back and smacks the ball down with as much force as she can. The ending velocity will majority of the time determine the winner of the rally. Due, to this the player really has to use a lot of force to make it harder for his opponent to pass back the ball.
Another example of velocity is serving a volleyball. A specific volleyball serve that uses velocity is in a jump serve. The player throws the ball into the air and as it comes down the player jumps in the air to gain momentum. She then uses her strength to hit the ball and gives it a topspin over the net. During the serve the ball seems to dip down. Also this serve allows the hitter to put more power into the hit without the ball landing out of bounds. On a serve like this there needs to be a higher velocity on the lower side of the ball, and a lower velocity on the top of the ball to create a topspin.
