The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. Most roller coasters consist of some basic parts: a chain lift, a catapult launch-lift (in newer coasters), and some type of brake mechanism. The first roller coaster originated in the early 80’s in Russia, it was built under the orders of a Russian empress named Catherine the Great in the Garden of Oranienbaum a Russian royal residence located in Saint Petersburg.
Roller coasters work by using gravity to move along the track, most think they have an engine inside that pushes them along the track like an automobile. The first part of a roller coaster is always a big hill; the biggest hill is always the highest point. The purpose of this is to gain two very important things gravitational potential energy, and kinetic energy. The reason these two things are important is because over the course of the coaster ride those two things propel the coaster, by exchanging for one another and sometimes combining. They can be exchanged for one another because at certain points on the ride the roller coaster may just have potential energy (like at the top of the first hill), or just kinetic energy (like at the lowest points) or maybe a combination of both kinetic and potential (like at all other parts) of the ride. Kinetic energy is relative to speed and potential energy is relative to height, so the kinetic energy will always be the highest at the lowest points and vice versa.
Like the info above states, there a 3 basic parts of a roller coaster I will now explain those. First is the chain lift; a type of lift hill found on roller coasters. It is the most common method of lift hill, and has been used for hundreds of years. A chain lift is propelled by one or two motors under the lift hill. As the motor turns, it moves the chain. When the train enters the lift hill the chain dog attaches itself, and it propels the car forward. Second is the catapult launch-lift; a...
