There are many animations and graphics available on the web that illustrate various aspects of differential equations. We are collecting a few that have been recently tested to work on current browsers and have potential applicability to physics classes; please feel free to suggest more.

 

• Falstad offers graphical solutions to some differential equations common in physics and applied mathematics
