Answer to Question #277485 in Mechanics | Relativity for JMD

Question

You answered me in a previous question that, in a scenario in which two objects A&B are side by side, then a force is applied to B to accelerate B away from A, then the force is removed from B so that B travels away from A at a constant velocity, that time, in reality, will move slower in B than A.

I would like to ask a follow up question.

In the scenario, if the two objects return to rest in regard to one another, (at some distance apart from each other) either by a reverse force being applied to B until it slows to a stop in regard to A, or a force being applied to A accelerating it in the direction of B until it reaches the velocity of B, can we say that time will again pass at the same rate for A&B, but that less time will have passed in B than A? I.e., clocks that were synchronized prior to the initial force will again be synchronized but the clock in B will read behind the clock in A.
