Roller coasters have no engines. Essentially a roller coaster is a gravity-powered train. The movement of a roller coaster is accomplished by the conversion of potential energy to kinetic energy. The roller coaster cars gain potential energy as they are pulled to the top of the first hill.

Do roller coasters run on electricity?

The train on a powered coaster usually picks up electricity from contacts in the rails (similar to an electric locomotive or a monorail) and may contain multiple motors. Some powered coasters are powered by a flexible cable connected to the train.

What do roller coasters run on?

Gravity is the force that pulls things to the ground. Roller coasters rely on gravity to take them to the end of the track. This involves two types of energy, potential energy and kinetic energy.
