Hey, I'm having some difficulty in understanding circular motion and it's forces. Here is the situation I'm on: Imagine you are on a smooth turn-table with smooth shoes and the table starts spinning. Because of inertia, and because the frictional force is not nearly enough to keep you going in a circle, you'll start moving in a more/less straight line towards the rim of the table. Now lets say the table had a fence along the rim, and you eventually bump into the fence and you're forced to move in a circular path. Is the perceived gravity the same as the centrifugal force in this case? Do you experience a centrifugal force in situation (a) where you didn't hit the fence yet and (b) at the fence? My understanding is that the centrifugal force is purely you're tendency to move tangentially. So since there is no or little resistance to that in situation (a), you don't experience anything. In (b) however, you will experience a force radially outward (??) - Why? It seems like centrifugal forces are similar to the backward force that you experience when you accelerate inside a car.
