What myPhysicsLab is
myPhysicsLab is a free collection of interactive physics simulations and JavaScript classes for building animated physics models. Simulations run in real time and let users drag objects or change parameters such as gravity. The library lists around 50 examples, including pendulums, springs, collisions, roller coasters, and rigid-body models. Many simulation pages explain the mathematics behind them. Users can customize models with EasyScript or JavaScript in a browser and text editor, then share a setup through a URL that embeds EasyScript. Numeric data can be retrieved through VarsHistory, JavaScript, or collision-data scripts. Downloadable versions support offline use. The software is open source under the Apache 2.0 License, with source code on GitHub. Simulations use dimensionless units, so values need to be interpreted consistently within each model. Building from source requires TypeScript, esbuild, Perl, and GNU Make. The project began in 2001 and is based in Seattle, Washington.
Who it suits
It suits learners, educators, and anyone exploring or building interactive physics models. The explanations of the mathematics may be useful in teaching, while EasyScript and JavaScript allow customization.
