For our experiment, we are dealing with two main questions.
1. What is the amount of force needed for the best spike?
2. What is the best angle of your arm and position of your hand to deliver the best spike?
The best kind of spike is one that goes straight down quickly on your opponent's side and is too difficult for your opponent to counter.
We can perform this experiment using Mr. Dickie's force plate, accelerometer, and slow-motion video camera. We will also be using a volleyball, court and net, stopwatch, and two willing volleyball players, a setter and a spiker. We will run three separate tests, with five trials in each.
1. The first test will consist of the player spiking the ball and measuring the amount of force behind it with the force plate. We will also measure the speed of the ball. By analyzing the results, we can determine what is the optimal amount of force needed to deliver a spike that no opponent can counter.
2. The second test will involve the player spiking the ball with her arm at different angles as she hits the ball. We will record the angles with the camera and analyze them on the computer. For each arm angle, we will analyze the time, amount of spin, and the speed of the volleyball.
3. For our final test, we will perform it similarly to the second test. This time, instead of measuring the angle of the arm, we will determine which position on the ball is the best to hit; for example, center, bottom, ect. We will record the trials with the camera and also analyze them on the computer. We will be measuring the time it takes to deliver the spike, the amount of spin on the volleyball, and the speed.
