Amusement park ride

Amusement rides, sometimes called carnival rides, are mechanical devices or structures that move people to create enjoyment.

Flat rides are usually considered to be those that move their passengers in a plane generally parallel to the ground, such as rides that spin around a vertical axis, like carousels and twists, and ground level rides such as bumper cars and The Whip.

Gravity rides are those where gravity is responsible for all or some of the movement, and where any vertical movement is not about a fixed point, such as roller coasters and water slides.

Vertical rides usually move their passengers in a vertical plane and around a fixed point, such as Ferris wheels, Enterprise, and Skydiver.
