Com Padre Digital Library: Open Source Physics: Multiple Slit Diffraction Model

This site from Open Source Physics offers a file with a simulation of Kepler's theory of planetary motion, tested with the Earth rotating around the sun and another planet of the user's choosing. The download requires Java.

Variation on the standard Atwood's Machine model, where one hanging mass swings like a pendulum and the other remains stationary. Manipulate the conditions and observe the results.

A bar magnet model built by placing a group of magnetic dipoles along the magnet. This simulation shows the magnetic field of a bar magnet, and has a movable compass which shows the magnetic field values.

Simulation analyzing the motion of a rotor that is repeatedly kicked. Adjust the settings for kick strength and speed and observe the results.

Simulation exploring the effects of gravitational, buoyant, and drag forces upon a sphere as it falls through a liquid.

This downloadable java simulation models the 2D energy eigenstates of a particle trapped in a very deep two-dimensional circular well.

Adjust to conditions of a double pendulum model and observe the results in an accompanying graph.

A double pendulum model where the angles and angular velocities can be manipulated and the effects observed.

A simulation that permits exploration of a standing wave inside a pipe that can be open or closed at either end. The user can adjust the number of wave nodes.

What's wrong with this model? Students expect simulations to show factual science concepts, but these particular simulations are intentionally built incorrectly. The objective is to find where the physics concerning electric fields is...
