Simply in design, this lesson plan was created by Deborah Lojkutz of Joliet West High School, the objective of this activity is to teach students the concept of periodic motion and relate it to the movement of a...

This simulation provides a realistic virtual mass-and-spring laboratory. Users can explore spring motion by manipulating stiffness of the spring and mass of the hanging weight. Concepts of Hooke's Law and elastic...

This website contains a Flash applet which simulates the motion of a vibrating string as well as ideas for activities involving this simulation. The end of the string can be moved using the mouse or driven by an...

Funded by grants from The William and Flora Hewlett Foundation and the National Science Foundation, the Physics Education Technology (PhET) site features many well-designed and engaging physics and chemistry simulations...

This JAVA applet solves the time-dependent Schrödinger wave equation for a gaussian wave packet incident on a square barrier or well. The height of the barrier (depth of the well) relative to the mean energy of the...
