Test how mass, velocity and elasticity affect one- and two-dimensional collisions.
🎮 Try It
Drag the balls and their velocity arrows, change each mass, and adjust elasticity from sticky to bouncy. Play or step through the collision. Turn on velocity vectors, path trails or more data, and compare the momentum and kinetic-energy readouts.
🎯 Your Mission
Set up two collisions with the same starting masses and velocities but different elasticity. Predict which readout will change differently after impact, then test frame by frame.
🌍 Real-World Connection
Engineers study collisions when designing vehicle crumple zones and sports safety equipment.
