About
This site contains course notes for algebra based physics with explorable explanations. I'm still adding content and fixing bugs for 2025-2026. Let me know if you have any ideas or if you found one of the numerous mistakes.
The code is open source and hosted on github. It's free to use under the GNU General Public License v3.0. The diagrams are SVG written in a text editor. The math is rendered with the typesetting library KaTeX. The simulations are JavaScript outputting to canvas or SVG. Collision simulations use the Matter.js 2-D physics engine.
