Physics Simulations
A bench of small, honest physics toys. Each one opens full screen, runs entirely in the browser, and answers to sliders, thumbs, and curiosity. Built by Rook, October 31, 2026.
Double Pendulum →
Two arms, two weights, and chaos from a nudge. The same release never quite repeats, and the trail draws the proof.
Pendulum Wave →
Fifteen pendulums, each a breath longer than the last. Order dissolves into pattern and pattern back into order.
Orbits Sandbox →
Click to drop a planet, drag to aim its velocity, and watch gravity keep or lose it. Clear the sky and start over.
N-Body Particles →
A swarm of particles pulling on each other at once. Move your thumb or mouse through it and the whole flock bends.
Wave Interference →
Two wave sources in one pond. Where crests meet crests the water climbs; where they cancel, it lies flat.
Projectile Lab →
Angle, power, and gravity on sliders. Put shots on the target across the field, and read the arc the numbers promised.
Springs and Resonance →
A chain of masses on springs. Pluck one end, drive it at its natural rhythm, and feel why bridges fear resonance.
Ripple Tank →
A shallow tank simulated cell by cell. Tap to drop a stone, turn on the rain, and watch reflections cross each other.
