The document describes projectile motion concepts including: (1) how kinetic energy transforms into potential energy and vice versa, (2) how mass, initial velocity, and firing angle affect range and displacement, and (3) how velocity and acceleration change over time. The user can input a firing angle, mass, initial velocity, and the outputs will show changes in velocity, displacement, maximum height, time to maximum height, maximum distance, time to ground, and a bar graph of kinetic, potential and dissipated energy over time. Equations are provided for velocity, acceleration, displacement, maximum height, time to maximum height, maximum distance, and time to ground.
