This Java applet simulates a 2 dimensional gas of hard spheres. It illustrates several important concepts in statistical mechanics/kinetic theory, such as: mean free path and average time between collisions, the approach to thermal equilibrium and the Maxwell-Boltzmann speed distribution, and the question of macroscopic irreversibility vs. microscopic reversibility.   less

A comparison of a mass-pulley system including and neglecting the inertia effects of the pulley. An interactive program designed to give students the opportunity to see an animation of a dynamics problem and the ability to construct free body and kinetic diagrams. The program tracks and checks the students selections for free body and kinetic diagram components. Other Author: Mark R. Eversden   less

This web-based software teaches the user concepts about treatment of the basic principles of semiconductors. The topics covered in this software include periodic structures, lattice waves, electronic states, static and dynamic properties of solids, electron-electron interaction, transport and optical properties. The software contains information on the MATLAB Examples: - Energy Bands - Simple Cubic Lattice - Free-electron model - Nearly-free electron model - Tight-binding model - Energy Bands - Face Centered Cubic Lattice - k-vectors in Brillouin zone - Reciprocal lattice vectors for fcc lattice - Free-electron model - Tight-binding model - Lattice Vibrations - Phonon Dispersion Curves - Monatomic fcc lattice - Monatomic bcc lattice This software was originally cataloged at http://www.mathworks.com/products/education/texamples/prodexamples.shtml.   less

This courseware provides a simulation that shows gravitational free fall. It shows a ball next to a measuring stick and a clock that times how long it takes the ball fall the length of the stick. The user is given the option to change the graviational force on the ball to that on the moon or mars.   less
