Multi-Pendulum — Chaotic motion under gravity. Trails show each bob's path; bright dots mark close encounters between bobs. Drag balls to reposition. Add up to 10 dots.
This page shows an interactive multi-pendulum animation. You can add up to ten bobs and drag any bob to reposition it. Colored trails show their paths. When two masses pass very close, a bright mark appears at that location. If your system requests reduced motion, the animation runs more gently.
