Ok, centers of mass will move away at the same speed. The push at the edge will make the spinning one rotate less, the not spinning one rotate more. Thank you.
Then, in the case of the two wheels (the spinning one and the not spinning one), with the centers moving according to F=mA , would each of the ends (on the same side) move at the same speed?
I understand that. But let me give another example: two parallel bycicle wheels (only one spinning, the same repulsive force as in the previous example). What means then stability if they move away at the same speed?
Let's say each pipe is 1 meter long. They are lying parallel. One pipe is spinning around the direction of its length. At the end of each pipe there is some kind of switchable magnet. So, a repulsive force is switched on. The pipes' ends would get apart, but for the spinning one, that means...
Yes, two lying parallel pipes, but only one is spinning. The repulsive force being applied between them at the extremity of the pipes. I can imagine the pipes getting apart, but the pipe at rest moving with a greater speed that the pipe that is spinning. Is this correct?
But if the force is applied at the end, wouldn't that change the plane of rotation and therefore wouldn't the spinning pipe offer more resistance to movement?
Like two pipes laying side by side (one of them is spinning) and the repulsive force being applied at the end. Would they get apart at the same speed then?
Consider two bodies, A and B, of equal mass set at a short distance. Body A is spinning and body B is at rest. Then, through some kind of electromagnetic device, a strong repulsive force is established between them. Will both be displaced at the same speed?
