Fowler's Physics Applets - These supplement physics courses taught by Michael Fowler at U of Virginia. They include Newton's cannon, Brownian motion, Rutherford scattering, and collisions in two dimensions.
Interactive Physics and Math with Java - A set of more than 20 scientifically accurate educational applets which mostly cover the course of Introductory Physics or material close to it. This site is mirrored a number of places on the net.
Non-Destructive Testing - Introduces four dynamics principles that can be applied to non-destructive testing: Snellís law, wave reflection, ultrasonic detection probe and radiography. Uses Java applets.
Nori's Physics Page - Java applets and Quicktime movies of physics simulations such as solar system, ideal gas, wave interference, and the Doppler effect.
Nuclides 2000: The Radionuclide Portal - Allows the simulation of the radioactive decay of over 2000 radionuclides using standard colour schemes (Karlsruhe, Strasbourg, General Electric). Basic decay data can be viewed by holding the mouse over a nuclide and consists of half-lives, modes of decay, and branching ratios. "Blinking" nuclides indicate strong gamma emitters with energies above a user-definable threshold value.
PBS.org - Transistorized! Web Site Interactives - Features two interactive games related to the development of transitors. The object of the Periodic Puzzle is to line up tiles to match a section of the periodic table of the elements. The Wafer Maker is a fast-paced game where the user grows silicon crystals to make transistors.
The Pendulum Lab - Examine the dynamics of rigid pendula. Includes explanatory text.
Physics 2000 - An interactive journey through modern physics. Have fun learning visually and conceptually about 20th century science and high-tech devices. Uses java applets.
Physics at Appleby College - A comprehensive collection of Java Applets on waves, sound, light and optics. Suitable for high school physics students.
Physics Illuminations - A collection of Java applets packaged with explanatory text for use as conceptual homework or student self-study in introductory physics.
The Physics of Pole Vaulting - Using very simple physics principles, this program estimates how high you could theoretically vault based on how tall you are and how fast you can run, assuming you had the proper training and optimal efficiency.
Physlet Problems - Physics applets plus the source code. Links to other applet sites and authors are here as well.
Reaction Time Measurements - Measure the time between viewing a red light and reacting to that light. Calculates distance traveled in that time.
