The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. LaMarcus Adna Thompson patented the first coasters on January 20, 1885. In essence a specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more inversions (such as vertical loops) that turn the rider briefly upside down. The track does not necessarily have to be a complete circuit, as shuttle roller coasters exhibit. Most roller coasters have multiple cars in which passengers sit and are restrained. An entire set of cars hooked together is called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.

In what may be a practical application, NASA has announced that it will build one to help astronauts escape the Ares I launch pad in an emergency.

Etymology

There are several explanations of the name roller coaster. It is said to have originated from an early American design where slides or ramps were fitted with rollers over which a sled would coast.Steven J. Urbanowicz (2002). The Roller Coaster Lover's Companion. Kensington, New York: Citadel Press. 4. ISBN 0806523093. This design was abandoned in favor of fitting the wheels to the sled or other vehicles, but the name endured.

Another explanation is that it originated from a ride located in a roller skating rink in Haverhill, Massachusetts in 1887. A toboggan-like sled was raised to the top of a track which consisted of hundreds of rollers. This Roller Toboggan then took off down gently rolling hills to the floor. The inventors of this ride, Stephen E. Jackman and Byron B. Floyd, claim that they were the first to use the term "roller coaster."Scott Rutherford (2000). The American Roller Coaster.

The term jet coaster is used for roller coasters in Japan, where such amusement park rides are very popular.Robb and Elissa Alvey. "Theme Park Review: Japan 2004", themeparkreview.com. Retrieved on March 18, 2008.

History

Main: History of the roller coaster

"Russian Mountains"

The oldest roller coasters descended from the so-called Russian Mountains, which were specially constructed hills of ice, located especially around Saint Petersburg. Built in the 17th century, the slides were built to a height of between 70 Some historians say the first real roller coaster was built under the orders of Russia's Catherine the Grhe Gardens of Oranienbaum (today Lomonosov) in Saint Petersburg in the year 1784. Other historians believe that the first roller coaster was built by the French. The Les Montagnes Russes à Belleville (The Russian Mountains of Belleville) constructed in Paris in 1812 and the Promenades Aériennes both featured wheeled cars securely locked to the track, guide rails to keep them on course, and higher speeds.
