Collision

Smash two balls together! Change their size and speed to see what happens when things crash.

Forces & Momentum

Bounce

Drop a ball and watch it bounce! Turn up gravity to make it fall faster, or make it super bouncy.

Gravity & Energy

Three-Body Orbit

Three objects in space pulling on each other with gravity. Watch them dance in crazy orbits!

Gravity & Chaos

Gravity Slingshot

A tiny space probe flies past a planet and speeds up — just like real NASA missions!

Orbital Mechanics

Double Pendulum

Two swinging arms connected together. Looks simple, but tiny changes make it go wild!
