Analyze object orbits with this simulation. Schwarzschild Particle Energy program simulates orbits of objects around a black hole using the Schwarzschild metric. It also displays a plot of the effective potential well in which the orbiting particle resides. The user can change the orbiter's state by entering new energy and angular momentum values and dragging the marker to different positions. The default configuration is a circular orbit.
