The ride often begins as a chain and motor (or other mechanical device) exerts a force on the train of cars to lift the train to the top of a very tall hill. Once the cars are lifted to the top of the hill, gravity takes over and the remainder of the ride is an experience in energy transformation.

Lift hills usually propel the train to the top of the ride via one of two methods: a chain lift involving a long, continuous chain which trains hook on to and are carried to the top; or a drive tire system in which multiple motorized tires (known as friction wheels) push the train upwards.

For most roller coasters, the gravitational potential energy of the cars at the peak of the first hill determines the total amount of energy that is available for the rest of the ride. Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy.
Chain Lift – This is the most traditional way of getting the train to move up the lift hill. ... Catapult-launch Lift – This is another way of moving the train up a hill in newer roller coasters. ... The Brake System – A roller coaster uses a brake system to slow down or stop it.
Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.
It suggests that the chances of being killed on a rollercoaster are just one in 170 million, while the injury odds are approximately one in 15.5 million.
The potential energy of the roller coaster when it is at the top of a hill is converted into kinetic energy as the roller coaster speeds down the hill. As the roller coaster goes up another hill, it slows down. The kinetic energy is converted into potential energy.
