Electric Field Hockey
An absolute classic – guide an electric charge to the goal using only other electric charges. Created by PhET.
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.
