Physics: Virtual Labs
These sites offer virtual lab experiments to illustrate the basic concepts of physics. Students can study the reaction of objects to forces, the behavior of light, and many other introductory physics concepts.
The Pendulum Lab
This site offers interactive pendulum experiments. Experiment with different forces on the pendulum for different results.
NTNUJAVA Virtual Physics Laboratory
This site includes a virtual lab/simulation and videos on converging/diverging lenses and mirrors. NOTE: You must download the Java Runtime Environment in order to view the simulation. NOTE: This site includes a discussion board.
Interactive Physics Modules
Here are interactive tutorials with some elements of lab experiments on mass, volume and density, electricity and magnetism, states of matter, plasmas, energy, and fusion.
This site contains several java applets illustrating common physics problems.
Here is a collection of physics applets on astrophysics, energy & environment, mechanics and thermodynamics.
