A Free Particle Interactives
A set of Desmos simulations covering a wide range of physics including many about mechanics – an excellent resource for teachers and students. Created by Michael Freeman.
Physics Simulations
Lots – hundreds at least – of small physics applets, around a wide range of topics, separated out into two semesters of college physics. Motion, thermo, EM, waves, and optics all covered. Created by Andrew Duffy.
Fowler’s Physics Applets
Collection of small physics simulations, many including nice explanations. Built by Michael Fowler.
myPhysicsLab
Lots of small simulations of things like pendulums and springs, where you can easily change the values, too. By Erik Neumann.
JavaLab
Just an amazing trove of science simulations built by middle school teacher, DJ Lee. I’m amazed at how much is covered here.
Index of Simulations
A spreadsheet pulled together for teachers of a categorized list of hundreds (wait, thousands!) of simulations you can find online, sorted by topic. An incredible resource organized by Helen Reynolds.
PhyPhox
Turn your phone into a physics lab. Graph things like acceleration, pressure, and magnetic field. Very powerful stuff. Created by RWTH Aachen University.
Wavemaker
A game about making waves, literally, and doing your best to match various patterns. Created by Universe & More.
Universe & More
A collection of interactive physics resources that are fun and easy to use. By Matthew Blackman.
