Several interesting physics applets written in Java 1.1.
Space Time Physics Lab - The Space Time Physics Lab applet demonstrates some physical effects of Einstein's Special Relativity, such as Lorentz contraction, time dilation, a light clock, Michelson-Morley experiment, Barn & Ladder paradox, and Car Headlight experiment.
LRC Circuit Lab - The LRC Circuit Lab applet displays a circuit with a inductor, resistor, and capacitor in series with an alternating current, showing the effects of resonance and complex impedance.
Electric Field - The Electric Field applet allows the user to set up a distribution of charges, upon which the applet will show the electric potential, electric field lines, and equipotential lines. In addition, the electric force will be observed through real time interaction of charges.
Moving Charge - The Moving Charge applet shows the field of a moving charge, and how it is concentrated in directions perpendicular to the motion. It also shows how information only propogates at the speed of light, and shows how the accelerating charge emits radiation by the compression of electric field lines, which produces an electromagnetic wave.
Magnetic Field - The Magnetic Field applet shows interactions between moving charges. It shows with a system of two wires why magnetic fields must exist in order for the postulates of relativity and charge invariance to be consistent with one another.
Inductance - The Inductance applet shows how EMF is induced in a loop by changing the magnetic flux through the loop. The different ways to change the flux includes changing the current in a nearby wire, changing a uniform background magnetic field, rotating the loop, moving the loop through a non-uniform field, and changing the size of the loop.
