In a single loop roller coaster, the train of open-air cars is slowly pulled up to the highest position along the ramp and the realized. The motor that pulls the train of cars up the ramp draw electricity from a generator.

In a single loop roller coaster, the train of open-air cars is slowly pulled up to the highest position along the ramp and the realized. The motor that pulls the train of cars up the ramp draw electricity from a generator.

However, the motor does not pull on the train when the trains roll downwards. Described how work is done to convert electricial energy into kinetic energy.
