A roller coaster is a type of amusement ride employing a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes, and other elements usually designed to produce a thrilling experience. Trains consist of open cars connected in a single line, and the rides are often found in theme parks around the world. Roller coasters first appeared in the 17th century, and LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, based on the Switchback Railway which opened a year earlier at Coney Island.
Cedar Point is a 364-acre (147 ha) amusement park located on a Lake Erie peninsula in Sandusky, Ohio, United States, owned and operated by Six Flags. It opened in 1870 and is considered the second-oldest operating amusement park in the US behind Lake Compounce. Prior to the merger with Six Flags in 2024, Cedar Point served as the "flagship park" of the Cedar Fair amusement park chain and hosted the corporate headquarters. Known as "America's Roller Coast", the park features 17 roller coasters, which ranks third among amusement parks in North America behind sister parks Canada's Wonderland (18) and Six Flags Magic Mountain (20).
Knott's Berry Farm is a 57-acre (2,500,000 sq ft) theme park located in Buena Park, California, owned and operated by Six Flags. In March 2015, it was ranked as the twelfth-most-visited theme park in North America, while averaging approximately 4 million visitors per year. The park features over 40 rides, including roller coasters, family rides, dark rides, and water rides.
A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position. Early forms of inversions were circular in nature and date back to 1848 on the Centrifugal railway in Paris. These vertical loops produced massive g-force that was often dangerous to riders. As a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression. In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters. Elements have since evolved from simple corkscrews and vertical loops to more complex inversions such as Immelmann loops and cobra rolls. The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster with 14.
Top Thrill 2 is a launched roller coaster located at Cedar Point in Sandusky, Ohio, United States. The ride originally opened as Top Thrill Dragster in 2003, becoming the tallest and fastest roller coaster in the world, as well as the first ever strata coaster – a height classification of 400 feet (120 m) or more. Designed by Werner Stengel, the Accelerator Coaster model from Intamin debuted with a height of 420 feet (130 m) and could accelerate from 0 to 120 mph (190 km/h) in 3.8 seconds. It was themed to Top Fuel drag racing, with the launch track designed to resemble a dragstrip, and it consistently ranked as one of the world's top steel coasters in Amusement Today's annual Golden Ticket Awards publication. Top Thrill Dragster's records were surpassed in 2005 by Kingda Ka at Six Flags Great Adventure.

Carowinds is a 407-acre (165 ha) amusement park primarily located in Charlotte, North Carolina. Owned and operated by Six Flags Entertainment Corporation, the park first opened to the public on March 31, 1973. Carowinds straddles the state line between North and South Carolina, adjacent to Interstate 77, with a portion of the park located in Fort Mill, South Carolina. The park has a sign telling guests where the state line lies. It was constructed at a cost of $70 million following a four-year planning period led by Charlotte businessman Earl Patterson Hall. Carowinds also features Carolina Harbor, a 27-acre (11 ha) water park that is included with park admission. Annual events include the Halloween-themed S-Carowinds and the Christmas-themed WinterFest.
Power Tower is a thrill ride located at two Six Flags parks in the US, Cedar Point and Valleyfair. The attractions are powered by air in large cylinders in which an aircraft steel cable, connected to the internal piston, travels and is also connected to the external rider car. Hydraulic cylinders at the base of the tower provide an extra measure of safety in case of a ride malfunction. Both rides were designed and manufactured by S&S Power of Logan, Utah. As of the 2020 season from their respective websites, both changed their height requirements from 52 inches (130 cm) to 48 inches (120 cm).
In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from either side of the body forming a Kármán vortex street. The fluid flow past the object creates alternating low-pressure vortices on the downstream side of the object. The object will tend to move toward the low-pressure zone.
Superman: Escape from Krypton, originally known as Superman: The Escape, is a steel shuttle roller coaster located at Six Flags Magic Mountain in Valencia, California. When it opened in 1997, it was the tallest roller coaster in the world, and its maximum speed of 100 mph (160 km/h) was tied for the fastest with Tower of Terror II, a similar roller coaster which opened two months earlier at Dreamworld in Australia. Both were the first to utilize Linear Synchronous Motor (LSM) launch technology to propel vehicles, although the intended opening date in 1996 at Magic Mountain was postponed due to issues with the launch system.
Xcelerator is a steel launched roller coaster located at Knott's Berry Farm in Buena Park, California, United States. Manufactured by Intamin and designed by Werner Stengel, it opened in 2002 as the company's first hydraulically-launched coaster and cost $13 million to construct. Following the early demise of Windjammer Surf Racers, a dueling roller coaster that briefly operated from 1997 to 2000, Xcelerator was soon announced as its replacement. It launches to a maximum speed of 82 mph (132 km/h) in 2.3 seconds and reaches a height of 205 feet (62 m).
