Hi all. This is not a homework question, I'm 33 and far away from homework. It is just a personal doubt. I've read a lot about these forces, even some answers from these forums but still can't make something out of them. What I've read: *Centripetal: a force that makes objects attracted to a rotating center. *Centrifugal: a pseudo-force that makes objects go away from a rotating center. This is what confuses me: in a merry-go-round the faster you gyrate, the greater the force to push you away from it (Centrifugal force). I have observed that personally when I was a kid. But the Centripetal definition states that it should be the other way around, and it isn't. So, if the earth is rotating at a high speed, why aren't we thrown out of it? -Gabriel.
