3-D Simulation for Assessing Projectile’s Motion with or without Air Resistance

Abstract

A Model was developed using JAVA Programming Language; this package simulates the motions of projectiles in air with air resistivity put into considerations or air resistance being ignored. Since air blows over the surface of the earth, thus Air resistance is said to be the linear function of the velocity. The model is based on the equations governing the trajectory of projectiles in motion; it is also coupled with arrows showing the direction of the wind on a 3-dimensional plane. With the use of a computer system, the motion of objects in real-life situations involving projectiles with or without air resistance can be simulated with this model. It is a good tool for the teaching of kinematical related course in tertiary institutions.
