Volleyball 2.0

Work: Work is when a force moves an object. In Volleyball, the force is the player and the object is the ball. When the player hits, spikes, or serves the ball it moves in the direction in which the force has been applied. Hopefully, that direction will be over the net, when spiking or serving, and to the target when bumping. Velocity: Velocity is the speed of movement. You can figure out the velocity of a volleyball shot by dividing the distance your ball traveled by the amount of time it took to get there. So let's say you serve a ball across the net from the behind the serving line, 30 feet, and the ball takes 1.5 seconds to get across the net. To find the velocity you would divide 30 feet by 1.5 seconds, which would be 20 fps. So the speed of movement, or velocity, of your serve was 20 feet per second. The higher the velocity the tougher it is for your opponent to hit the ball back to you. Which means, the faster your ball is traveling the harder it is to return. Acceleration: Acceleration is an increase in velocity. Let's say you've just served the ball, it's gone over the net, and is falling to the ground. As gravity pulls the ball to the ground, it accelerates. If you gently lob the ball over the net and your opponent sends a hard spike back at you, that's another example of acceleration. The ball's velocity increased when spiked back over the net, by your opponent, therefore it accelerated.
