Step 1 · Predict
Choose a collision type and set your initial values. Enter your prediction for momentum and kinetic energy conservation before pressing Run Trial.
Learning Objective
Determine whether momentum and kinetic energy are conserved in fully inelastic, partially inelastic, and perfectly elastic collisions. Use the sliders to set cart masses and launch velocities, run the trial, then compare initial and final values.
Step 2 · Collect
Watch the simulation and read the live kinematic states in the analysis panel, especially the values immediately before and after impact.
Step 3 · Compare
Use percent difference to judge conservation. In this simulation, close to 10% or less is acceptable.
