I have a question about uniform circular motion that is just confusing me. Maybe one of you can elucidate it for me. Say I am in a roller coaster car and I am travelling in a loop. At the top of the loop if my velocity is not great enough I should fall out of the loop but because the car is bolted to the track I will not. I have a seat belt on and it is keeping me from being planted into the ground. If the centripetal force is 576N and the force of gravity on me is 784N then wouldn't the seat belt have to support a force of 1360N? Thanks!
