Many people love roller coasters. Some people call them scream machines. They agree that riding a roller coaster is a thrilling experience. What you may not realize while you are going so fast is that a roller coaster has no engine. You are not being propelled around the track by a motor. A roller coaster moves on its own.

How do you think that can happen?

Answer:

Step-by-step explanation:

When your going up a track will pull up up but on the way down it is all gravity doing the work, since the cart if heavy it will go down fast and have enough momentum to do loops,turns, and go up small hills :)
