Waves: An Interactive Tutorial ` - Jan 10, 2016

This collection of interactive tutorials on Waves covers topics ranging from basic motion through chains of oscillators and non-linear waves. Each tutorial is built around an interactive simulation that can be run on a wide range of devices.

Interactive Video Vignettes ` - Jun 23, 2015

Video-based tutorials in introductory physics allow students to interact, answer questions, and explore

LTU: PHYSics appLETS (PHYSLETS) ` - Feb 11, 2015

This website contains a large collection of Physlet-based activities and illustrations for introductory mechanics and E&M, as well as some content for relativity and quantum physics.

Using Direct Measurement Video to Teach Physics ` - Dec 24, 2014

Direct Measurement Videos encourage active learning in introductory physics classes. Students can analyze real-world behavior using physics concepts and measurement tools included in the video. This material includes best practices for using these videos, a library of videos, and example class activities.

The Physics of Road Runner ` - Jun 1, 2014

This resource provides clips from Warner Brothers Road Runner and Coyote cartoons. Suggestions for use are included next to each clip. A Microsoft PowerPoint presentation based on the clips is also provided.

LTU Physlet: Presenting .. Your Equipotentials! ` - Nov 1, 2013

This applet shows the equipotential lines and the electric field lines for a single positive or negative charge, two equal positive or negative charges, two unequal like or unlike charges, and unequal unlike charges.

UVA Virtual Lab: Resistor Waterwheel Analogy ` - Dec 23, 2010

These pages provide a water model of an electrical circuit. In this case, the gerbil running in its wheel and the bucket pump are the equivalent of a battery. The water represents the electrons in the circuit. The height represents the voltage. The wheel represents the resistor. As the electrons fall from high to low, energy is available to do work.

PhET Simulation: Simplified MRI ` - Mar 12, 2010

This is an interactive simulation on the topic of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). The user can change the applied magnetic field and the RF signal and observe the effect on spins. In the NMR mode, the user can choose between various  from among several atoms. In the MRI mode, the user can elect to add a tumor to the head being visualized.

Lens (thick lens) and mirror ` - Jan 27, 2009

This applet allows the user to make a lens or a mirror and observe its effect on distant light. The user can change the thickness, the curvatures, the diameter, the index of refraction of the lens, and the index of refraction of the surrounding medium. Several special cases are pre-programmed and can be invoked by clicking on a link.

PhET Simulation: Geometric Optics ` - Dec 27, 2008

This interactive java application allows you to investigate the properties of converging lenses.  You can change the index of refraction, the diameter and the radius of curvature of the lens. You can also change the types of objects used and the types of rays shown.
