Homework Statement
At the top of the loop, we are in an upside down position, with our head being pointed towards the centre of the circle. As long as the ride is fast enough, it's impossible for us to fall out. But what happens if the ride slows down? if the rollercoaster slows down, the centripetal force is smaller. Which means the contact force from the seat will be smaller, right? if the velocity decreases further, the contact force at the top decreases to zero, since centripetal force is the sum of weight + contact/reaction force. If the rollercoaster slows down even further and the weight becomes greater than the required centripetal force, we are supposed to fall down.
Homework Equations
Why do we fall down if the weight becomes greater than the centripetal force? What is the physics behind this motion?
