Who doesn't love the heart-poundingfacts-paced thrills of a roller coaster ride?
Side friction roller coaster Ina mining company in Summit Hill, Pennsylvania constructed the Mauch Chunk Switchback Railwaya downhill gravity railroad used to deliver coal to Mauch Chunk, Pennsylvania — now known as Jim Thorpe.
Railway companies used similar tracks to provide amusement on days when ridership was low.
Perhaps the best known historical roller coaster, Cyclonewas opened at Coney Island in The Great Depression marked the end of the golden age of roller coasters, and theme parks in general went into decline. This lasted untilwhen the instant success of The Racer at Kings Island near Cincinnati began a roller coaster renaissance which has continued to this day.
Unlike wooden coaster rails, tubular steel can be bent in any direction, allowing designers to incorporate loops, corkscrews, and many other maneuvers into their designs. Most modern roller coasters are made of steel, although wooden coasters and hybrids are still being built.
It is said Roller coaster works have originated from an early American design where slides or ramps were fitted with rollers over which a sled would coast. Another explanation is that it originated from a ride located in a roller skating rink in HaverhillMassachusetts in 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". Contrastingly, in Russian, they are called "American mountains".
In Scandinavian languages and German, the roller coaster is referred as "mountain-and-valley railway". German also knows the word "Achterbahn", stemming from "FigurBahn", like Dutch "Achtbaan", relating to the form of the number 8 "acht" in German and also Dutch.

March Play media Video from inside a roller coaster car Helix at Liseberg in Gothenburg, Sweden The cars on a typical roller coaster are not self-powered. Instead, a standard full circuit coaster is pulled up with a chain or cable along the lift hill to the first peak of the coaster track.
The potential energy accumulated by the rise in height is transferred to kinetic energy as the cars race down the first downward slope. Kinetic energy is then converted back into potential energy as the train moves up again to the second peak.
This hill is necessarily lower, as some mechanical energy is lost to friction. Not all rides feature a lift hill, however.
The train may be set into motion by a launch mechanism such as a flywheel launch, linear induction motors, linear synchronous motors, hydraulic launch, compressed air launch or drive tire.
Such launched coasters are capable of reaching higher speeds in a shorter length of track than those featuring a conventional lift hill. Some roller coasters move back and forth along the same section of track; these are known as shuttles and usually run the circuit once with riders moving forwards and then backwards through the same course.
A properly designed ride under good conditions will have enough kinetic, or moving, energy to complete the entire course, at the end of which brakes bring the train to a complete stop and it is pushed into the station.
A brake run at the end of the circuit is the most common method of bringing the roller coaster ride to a stop. One notable exception is a powered roller coaster. These rides, instead of being powered by gravity, use one or more motors in the cars to propel the trains along the course.
If a continuous-circuit coaster does not have enough kinetic energy to completely travel the course after descending from its highest point as can happen with high winds or increased frictionthe train can valley: The train will then come to a complete stop in the middle of the track.
This, however, works somewhat differently on a launched coaster.
When a train launcher does not have enough potential energy to launch the train to the top of an incline, the train is said to roll back.As of , Leviathan is Bolliger & Mabillard's second tallest and fastest roller coaster, and the company's first giga coaster – a class of roller coasters with a height or drop that exceeds feet (91 m).
One cycle of the ride lasts about 3 minutes and 28 seconds. Layout. After leaving the station, the train turns degrees to the right, then begins to climb the chain lift hill.
