Explore the physics of motion

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!

Chaos Theory

Spring Chain

A chain of masses connected by springs. Watch waves travel through the chain!

Hooke's Law & Waves

Projectile Range

Launch a ball at any angle! See how far it flies and how drag changes everything.

Kinematics & Drag
v1 v2 orbit

Newton's Cannon

Fire a cannonball from a mountaintop. Go fast enough and it orbits the whole planet!

Inclined Plane

Roll a ball down a ramp with gravity and friction. See how angle and friction affect the slide!
