Provides canvas-based JavaScript physics demonstrations for classroom use, including a live special relativity simulator.
jsphys encapsulates a growing library of simulations and explanations of physical phenomena, from wave interference to special relativity.
jsphys provies a framework for relativistic demos, using predefined scenarios to demonstrate relativistic effects. Users can interact with the demos, changing their reference frames, zooming in and out, and changing the playback speed. Currently supported effects are:
Planned effects include relativistic beaming and arbirary object paths. The simulator will also support audio narration, allowing users to step through demonstrations as they listen to explanations of what they're seeing.
Send a pull request! The user interface could stand serious improvement, and our GitHub issue queue lists features and bugs that need to be worked on.
jsphys uses features like canvas and JavaScript typed arrays, requiring a recent browser. It has currently been tested on recent versions of Firefox, Chrome, Safari, and Internet Explorer.
A demo of the work-in-progress version of jsphys is available:
