Dev builds interactive physics playground teaching orbits by throwing balls at Earth
CurieuxExplorer · x · 2026-09-28
Developer CurieuxExplorer released an interactive physics playground where you learn orbital mechanics by slingshotting balls at Earth: too slow crashes, too fast escapes, and just right becomes an orbit — then you can switch gravity off mid-orbit and watch the object fly off in a straight line.
There are no lectures; discovery is the point. It works on phones and ships with scenarios like Newton's mountain, a feather in vacuum, a half-gravity planet, and rendezvous with a moving satellite. The author also shares a Claude Opus 5.5 link used to build it.
