In this video, we can see that rotating the paper somehow makes it less susceptible to being damaged. I can tell that the paper has some angular momentum. But how do we explain this phenomena in terms of energy transfer? It sort of remind me of how using simple equations, ( for momentum and energy) we can show that objects moving faster in a linear collision have less energy transferred to them. Is there an analogous description for 'rotating collisions'?
Moreover, would it be correct to say that the paper becomes harder when spinning very fast?
