Yes, in the tracks and the wheels the roller coaster cart rests on.
Each car of the train on the roller coaster has wheels that grab on to the top, the outside rail (most of them), and the bottom.

They wanted to make new kinds of roller coasters just like they wanted to make them higher.
It depends on th weight of the table, it could be 16, or trimline shades.
The science behind roller coasters is pretty simple. They actually go waaay back in history. Now at days, people use steel or metal to build it. They bolt it together and viola! A Roller Coaster! But one problem, the train that goes on it! The train that goes on it is a magnet and has wheels. The weight of the train and the chains on the roller coaster move it. Happy Searching! :)
James Plimpton invented the roller skates with 4 wheels. He was a great man. He had a brother and one sister. The place where the first roller skating rink was in a hotel dining room.

Friction, slows the roller coaster down to a slow enough pace that it eventually stops.
The theme park was invented first by people in Copenhagen Denmark (Tivoli Gardens), and then improved on by Walt Disney (Disneyland Anaheim, CA), because they wanted something more fun than roller coasters and ferris wheels. They wanted a place that adults and children could enjoy together.
The first roller coaster was actually a coal mining car in NY in 1895 that ran 18 miles down hill and would hit a 100 MPH. People came up to the hill where it was located and rode it down. Roller coasters became popular after WW1 and there were over 2,000 built in the United States in the early 1900's. In 1927 the Coney Island roller coaster opened. The early roller coasters were very dangerous and many people got hurt on them. They are called roller coasters because wheels are used for them to coast on a track. It is all done with gravity.
