Answer:
The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. ... The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill.
Answer:
a roller coaster works using gravity. the initial hill has to be high enough that gravity is able to produce enough momentum to complete the course.
