The GR Classical program simulates orbits of objects around a central mass using Newtonian mechanics. It also displays a plot of the effective potential well in which the orbiting particle resides. GR Classical is part of a suite of Open Source Physics programs that model aspects of General...

The Ejs Action for the Harmonic Oscillator model displays the trajectory of a simple harmonic oscillator by minimizing the classical action. The simulation displays the endpoints of the motion (t,x) which can be changed by using the textboxes or dragging, and displays the new trajectory as well...

The Momentum Space package is a self-contained file for the teaching of the time evolution and visualization of energy eigenstates and their superpositions via momentum space in quantum mechanics. The file contains ready-to-run OSP programs and a set of curricular materials. The material focuses...
