🧪 Bouncing Balls Physics (2D)

A flat Canvas 2D ball-pit: gravity, floor/wall restitution and mass-proportional impulse collisions between dozens of balls, with live sliders for gravity, bounciness, ball count and spawn rate.

This 2D companion runs the same ball-pit physics as the 3D original — gravity, floor/wall restitution and mass-proportional impulse collisions — on a flat Canvas view instead of an orbiting WebGL scene: a side panel exposes gravity strength, bounciness (coefficient of restitution), the target ball count and the spawn rate, while a live readout tracks total kinetic energy, average ball speed and the collision rate per second, making the effect of each parameter on the system directly legible instead of hidden behind a rotating camera.

2D Canvas ball-pit with gravity, wall/floor restitution and mass-proportional impulse collisions, tuned live via gravity, restitution, ball-count and spawn-rate sliders.
