Abstract

The Newtonian and relativistic dynamics of a low-speed bouncing ball system in a weak gravitational field are compared. My preliminary research shows that, contrary to expectation, the trajectories predicted by Newtonian, special relativistic and general relativistic mechanics from the same parameters and initial conditions will rapidly disagree completely if the trajectories are chaotic. Chaos is expected to also cause other dynamical predictions of the three theories, which I propose to study, to disagree. The feasibility of verifying which theoretical prediction is empirically correct will be explored. If general relativity is empirically correct as expected, the other two theories cannot be used to study the dynamics of a low-speed weak-field chaotic system. General relativity must be used instead.
