I wasn't sure whether this question belonged in relativity or QM, or even just plain classic. This forum seemed the best bet, but I am not using speeds near C - mere Galilean relativity will suffice here.
I have two objects, A and B
A is moving with velocity V and thus has kinetic energy E
B is stationary and has no kinetic energy
But now I put my foot down and accelerate until I am moving with velocity V, or, put another way, A is now stationary and B is moving at -V. Thus, now A has no kinetic energy and B has kinetic energy E.
So, how did the energy move from object A to object B? I touched neither and they are separated by vacuum. I am forever being told that energy is "real" and not just a convenient conservation constant, and that we can convert it to and from matter should the conditions permit, but if it's location depends on the observers velocity I am having trouble understanding that...
