I'm reading a science fiction book where a character is on a rotating space station orbiting Mars. She is running opposite to the spin at a speed where Mars is stationary overhead. Would this cancel out the artificial gravity caused by the rotation? If so, what would happen to her?
EDIT - I did look at the answer to a similar question after sammy suggested it, and while it is the same question, I still wonder about what would happen. If you're running against the rotation, you would probably begin to float. But then the moving air would catch you. I assume that you would then fall back to the "floor". Does that seem sensible?
