LC: If we have two accelerating frames accelerating at the same rate but in opposite directions, do the Laws of Physics transform according to the LT where v in the LT is now the instantaneous relative velocity of the frames at every time t? AG
It's not the "Laws of Physics" that transform. The LT describes the measurement of one system from another in relative motion. If one or both systems are accelerating; it applies to instantaneous measurements.
JC: take notice. These are the TWO frames I was referring to previously. Also, in answering the question posed in this thread, I don't think it matters if the acceleration is produced by a force or by gravity. This is what I conclude from Brent's diagram. Do you agree? AG
It doesn't matter as far as how the LT relates measurements in one system from the other. But it matters within each system whether it is accelerated or not (e.g. Coriolis forces) and gravity is not a force. Free fall is unaccelerated motion in GR.
