Nebraska-Lincoln Astronomy Applets
Various small astronomy simulations built by the University of Nebraska-Lincoln’s Astronomy Department.
Dan Schroeder Physics Educational Software
Physics education software created mostly by Dan Schroeder, some excellent simulations in here.
Bicycle
Long blog post about the physics behind bicycles. Full of interactives, and very cleanly done. Covers an absurd amount of mechanics. Created by Bartosz Ciechanowski.
Airfoil
A long interactive blog post about how a wing works, simulating the movement of air and pressure. The post gets into lots of related physics along the way.
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.
Interactive Molecular Dynamics
Particle simulation that is great for exploring thermodynamics, or Newtonian mechanics, gas laws, etc. Created by Dan Schroeder.
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.
