In the current paper we examine the “chase” between two test probes dropped radially and simultaneously from two different heights. We know that in the case of constant gravitational acceleration their separation is invariant and equal to their initial separation. Is this true for the realistic case of variable gravitational acceleration? We will present two working examples, one based on Newtonian mechanics, the other using the machinery of general relativity. The same methodology is used in both cases.
