hi i have been thinking about this scaling problem: Let me say a man and a cat jump from the top of a high building. both hit the ground, but as we all know the cat has a much higher chance to be alive after the collision. so is this caused by the biological or physical differences between the two bodies? or let me ask it in a different way, would this phenomenon also occur, if you would let a small cube and a big(and heavier) cube fall from a building? intuitively, i would say so. but where is the physical explanation for this?
