Roller coaster

The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. LaMarcus Adna Thompson patented the first roller coaster on January 20, 1865. In essence a specialised railroad system, a coaster consists of a track that rises and falls in specially designed patterns, sometimes with one or more inversions (the most common being loops) that turns the rider briefly upside down. The track does not necessarily have to be a complete circuit (the antonym of complete circuit is "shuttle"), though some purists insist that it must to be a true coaster. (Not all thrill rides that run on a track are roller coasters). Most coasters have cars for two, four, or six passengers each, in which the passengers sit to travel around the circuit. An entire set of cars hooked together is called a train.
