Rigid Body Collisions
Long-tail route · mechanics
Use this when collision response should feel like a rule set you can trust.
Physics/math explainer for 2D rigid-body collision resolution with vector geometry, normals, and relative-velocity intuition.
At a glance
Live interactive
The maintained version lives at the route linked here, with this garden note keeping the embed and editorial framing.
Best companion
Pair it with [[Bicycle]] when you want the next mechanics route after impulses, normals, and contact response start to make sense.
Time and level
About 10 to 15 minutes. Beginner friendly. Best if you want one compact physics route before the longer mechanical explainers.
