Tidal Acceleration

An example of tidal acceleration discussed in General Relativity. It shows a ring of particles free falling in a non-uniform gravitational field. Specifically 5 gram dice falling toward a 1000 kg “bowling ball”, time is speed up. The program Universe Sandbox was used in creating this simulation.

General Relativity. A few short lectures by Avi Rabinowitz, which give a good introduction to the ideas of GR.

Particles free fall along lines that pass through the center of the large mass.
