Physics Sandbox
Explore physics, motion, collisions, and interactive simulations through fun browser-based experiments.
Explore Interactive Physics
Physics Sandbox is a collection of interactive simulations designed for experimentation and discovery. Test gravity, collisions, momentum, chain reactions, destruction, motion, and other fascinating systems directly in your browser.
Each simulator offers a different way to experiment. Build a chain reaction, knock down dominoes, launch objects, play with ragdolls, destroy structures, or explore evolving patterns in Conway's Game of Life.
Learn Through Experimentation
Interactive simulations make it easy to see how different rules and forces affect the world around you. Change objects, settings, and conditions, then run the simulation to see what happens.
❓ Frequently Asked Questions
What is Physics Sandbox?
