Kinetic Energy Interceptor

This interactive simulation allows students to collide two objects and investigate whether momentum and/or kinetic energy are conserved in the collision process. To keep things simple, the simulation involves an isolated system where the objects collide along a single line. Use the sliders to set...

The STP TemperatureMeasurementLJ program simulates the exchange energy between a demon and a system of particles interacting via the Lennard-Jones potential. The program shows the kinetic temperature of the system as a function of time, and the energy distribution of the demon. The purpose of...

The Molecular Dynamics Adiabatic Piston model shows two gas samples within a horizontal cylinder that is divided by an insulated piston that moves without friction. It is a supplemental simulation for an article by Eric Gislason "A close examination of the motion of an adiabatic piston" in the...
