Partnership for Integration of Computation into Undergraduate Physics

Three simulations for energy demos and experiments in Mechanics. ### Simulation 1: Ball on Trampoline Simulates a ball launched vertically from a spring (trampoline) which flys up into the air and returns to spring, re-compressing it. Elastic potential energy, gravitational potential energy, and kinetic energy are constantly changing but their sum remains conserved. ### Simulation 2: One ball launched up a ramp with a spring This simulation features a ball launched horizontally by a spring. The ball travels across a floor and then moves up a ramp. You can vary the spring constant, compression distance, and ball mass to observe the effects on the ball's maximum height and speed. ### Simulation 3: Two balls launched up a ramp Similar to Simulation 2, this version launches two balls simultaneously. This allows for a direct visual comparison of how varying parameters, such as spring constant, compression distance, and ball mass, affects each ball's maximum height and speed.
