The physics of roller coasters comprises the mechanics that affect the design and operation of roller coasters, a machine that uses gravity and inertia to send a train of cars along a winding track. Gravity, inertia, g-forces , and centripetal acceleration give riders constantly changing forces which create certain sensations as the coaster ...
A brake run on a roller coaster is any section of track that utilizes some form of brakes to slow or stop a roller coaster train.The most common type is the friction brake, often called a fin brake, which involves a series of hydraulic-powered clamps that close and squeeze metal fins that are attached to the underside of a coaster train.
A giga coaster is a type of roller coaster with a height or drop of at least 300 feet (91 m). [48] The term was coined during the construction of the Millennium Force, a roller coaster built by Intamin on Cedar Point amusement park.

The planning, design and development phases of Millennium Force took place over five years, from 1996 to 2000. [4] The first rumors that a new record-breaking roller coaster would be built at Cedar Point, which included speculation about a ten-inversion roller coaster from Bolliger & Mabillard and an Arrow Dynamics MegaLooper, began circulating in early 1998.
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many ...
Centrifugal Railway was the name of a number of early looping roller coasters that were built in Western Europe in the middle of the 19th century. These rides were very similar in their basic design to many modern day shuttle roller coasters (i.e., they did not make a complete circuit), but with only one lift hill and no launch.
Unlike the other two fictitious forces, the centrifugal force always points radially outward from the axis of rotation of the rotating frame, with magnitude , where is the component of the position vector perpendicular to , and unlike the Coriolis force in particular, it is independent of the motion of the particle in the rotating frame.
