What PhysicsHub is

PhysicsHub is a free web application for learning physics through interactive simulations, theory, and reference material. Its library lists 18 simulations covering kinematics, dynamics, gravity, collisions, optics, and electromagnetism. Users can change variables such as mass, gravity, and spring constant and see forces recomputed in real time. Simulations are tagged for middle school, high school, university, or tool and demo levels. The Physics Formulary lists 60 formulas across 10 domains, with calculators for 48 formulas. PhysicsHub also publishes visual interactive guides and 11 blog posts. Its features include live controls alongside theory, math-accurate physics engines, and light and dark modes. The project describes itself as open source under the MIT License, allowing users to inspect code and fork the repository. Simulations are free forever, require no login, and contain no ads. Community participation includes questions, suggestions, contributions, bug reports, and translations through linked Discord support.
