The forces experienced by the rider are constantly changing ...

Kingda Ka, the world's second fastest roller coaster, has a design speed of 128 mph (206 km/h), seven pumps, four accumulators, and 32 turbines. The system as a whole is capable of producing up to 20,800 horsepower (15.5 MW) for each launch, although a typical launch uses less than 10,000 horsepower (7,500 kW).
Some roller coasters utilize unique wheel configurations: On Superman: Escape from Krypton , manufactured by Intamin , located at Six Flags Magic Mountain , the cars do not use typical side friction wheels along the rails, but rather uses a thin steel rail mounted in the center of the track to keep the train centered, while running and up-stop ...
