Explore science through interactive simulations
Experiment with mathematics and physics using dynamic simulations that run directly in your browser. Visualize calculus, motion, gravity, and other scientific ideas as interactive experiments.
Interactive experiments
Real physics. Simple experiments.
Each simulation runs a mathematical physics model inside the browser using real equations from classical mechanics. Change parameters such as gravity, height or velocity and instantly observe the results.
