Multimedia instructional tools for the physical sciences are rather in vogue these days, and a number of universities and colleges have developed creative resources in this area. One such set of resources happens to be the Physics Applets collection, created by staff members at the University of Oregon's physics department. The interactive applets are divided into four sections, including mechanics, thermodynamics, astrophysics, and energy & environment. In total, there are over thirty different applets, and they include those that illustrate the concepts of potential energy, Kepler's Third Law, and atomic emission. The site also includes a listing of credits, a help section, and information about this initiative.
