What holds a roller coaster on the track?

For a roller coaster, gravity pulls down on the cars and its riders with a constant force, whether they move uphill, downhill, or through a loop. The rigid steel tracks, together with gravity, provide the centripetal force needed to keep the cars on the arching path as they move through the loop.

Roller coaster wheels are designed to prevent the cars from flipping off the track. They secure the train to the track while it travels through fancy loops and twists. When you go upside down on a roller coaster, inertia keeps you from falling out.

Chain Lift The motor turns the chain loop so that the chain continually moves up the hill like a long conveyer belt. The coaster cars grip onto the chain with several chain dogs, which are mounted to the underside of the rollercoaster cars.

Chain Lift – This is the most traditional way of getting the train to move up the lift hill. They resemble a bike chain or long conveyor belt and are responsible for the clacking sound that's heard when going up a hill. Catapult-launch Lift – This is another way of moving the train up a hill in newer roller coasters.

Wooden tracks are held up by large, strong frames with crossed beams. These frames are supported by “bents”3 which support the structure. In roller coasters, bents are made of pairs of evenly-spaced boards attached to the main supports. These main supports are attached to concrete foundations on the ground.

Riders held in by over-the-shoulder restraints. Over-the-shoulder restraints (often abbreviated to OTSRs) are U-shaped restraints which swing down from behind the rider's head to secure the torso. Some also have a belt, which secures the bottom of the restraint to the seat, passing between the rider's legs.

The force of forward momentum slowly depreciates throughout the ride. At the end of the ride friction between the wheels and the track or wheels and their brakes slowly wins out and the cars come to a halt. The harder the brakes are applied the more rapidly the coaster will come to a stop, also known as deceleration.

Two of the most significant are friction and air resistance. As you ride a roller coaster, its wheels rub along the rails, creating heat as a result of friction. This friction slows the roller coaster gradually, as does the air that you fly through as you ride the ride.

The most significant force acting on your body during a roller coaster ride is the force of gravity. When you are upside down, gravity is pulling you downwards, but your body is being pulled upwards by the coaster's momentum, which creates the sensation of weightlessness or zero-g that riders often experience.

Like any train, a roller coaster needs a brake system so it can stop precisely at the end of the ride or in an emergency. In many roller coasters, there are also spots along the track where the train is slowed or stopped deliberately.

Anti-rollback device The familiar "click-clack" sound that occurs as a roller coaster train ascends the lift hill is not caused by the chain itself. The cause for this noise is actually a safety device used on lift hills?the anti-rollback device.

Attractions are designed with natural forces in mind including earthquakes. Typically the attraction will just sway like any building designed to handle earthquakes would. It would all depend on the magnitude of the earthquake, the location of the roller coaster, and exactly how well the roller coaster was built.
