Roller Coasters The main energy transfers that happens as a “car” travels along the track from the start of the ride to the end. 1. The main energy transfers are between gravitational potential energy (GPE) and kinetic energy (KE)‚ and the eventual decrease of mechanical energy as it transforms into thermal energy. Roller coasters often start as a chain and motor exercises a force on the car to lift it up to the top of a very tall hill. At this height‚ GPE is at its highest‚ as we can see

Physics of roller coasters | | Simply speaking‚ a roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track.[1] This combination of gravity and inertia‚ along with G-forces and centripetal acceleration give the body certain sensations as the coaster moves up‚ down‚ and around the track. The forces experienced by the rider are constantly changing‚ leading to feelings of joy in some riders and nausea in others. The basic principles of roller coaster mechanics
