I'm in my first year of physics and I'm having trouble understanding some aspects of centripetal force. When someone is spinning rapidly on, say, an amusement park ride, they tend to be pushed outward the faster they go. Is this the tangential velocity? Or does it involve a different aspect of uniform circular motion? And if so, how do I calculate it? EDIT: I know basic equations such as Centripetal acceleration = velocity squared / the radius, and the velocity = the circumference / the time to complete 1 revolution. And this is only homework related insofar as I will understand it better; I'm not seeking an easy answer.
