Roller coasters with loop-the-loops are generally rides that appeal to thrill seekers, however without the use of dynamics, these rides would not be able to function. A roller coaster loop-the-loop is a type of large scale centrifuge, as one approaches the loop, the rider's inertial velocity is straight ahead. However the track of the roller coaster keeps the car and therefore the rider, from travelling in a straight path. The force of a rider's acceleration pushes them from the coaster-car floor, and their inertia pushes them into the car floor. As one travels upside down on the loop, he or she's own outward inertia creates a false sense of gravity that stays fixed at the bottom of the car. Thus in most loop-the-loops,
