Abstract
The forces exerted by volleyball players when they hit the ball from their own realm over the net to the realm of the opposing side could be calculated and a model was designed with the condition that the ball must not leave the court area. This research created the instructional material using a mathematical program to describe the movement of volleyball. The research revealed that the volleyball batter force was a mathematical function of applying the initial force to time as it related to the logarithmic, exponential and trigonometric functions. Newton’s second law of motion was used to calculate time-dependent velocity and horizontal and vertical displacement of the volleyball under two types of applied initial force. Each force was integrated to find the initial velocity. The results defined the vertical displacement as a horizontal function. A graph was plotted between horizontal displacement (X) and vertical displacement (Y).
