⚽ Physical Sandpit — 2D Ball Collisions, Restitution and Energy Balance

2D side-view companion of the physical sandpit sim: discs with gravity, wall and sand-floor restitution, impulse-based ball-ball collisions, kinetic and potential energy graphs and checks of the bounce-height ratio, restitution coefficient and momentum.
