Physion
physion.net
A free, browser-based 2D physics simulator where users draw objects, link them with joints and springs, simulate liquids and soft bodies, and script behavior with JavaScript.
Physion provides an accessible physics sandbox that runs entirely in the browser, requiring no installation. Scenes are built by drawing shapes and connecting them with joints and springs, allowing for quick experimentation with mechanics. The optional JavaScript scripting extends its utility for more complex or automated simulations, making it a practical tool for both learning and prototyping.
