What makes a roller coaster exciting speed or acceleration?

At the top of a roller coaster, the car goes from moving upward to flat to moving downward. This change in direction is known as acceleration and the acceleration makes riders feel as if a force is acting on them, pulling them out of their seats.

The thrill of roller coasters is not due to their speed, but rather due to their accelerations and to the feelings of weightlessness and weightiness that they produce.

Two of the most significant are friction and air resistance. As you ride a roller coaster, its wheels rub along the rails, creating heat as a result of friction. This friction slows the roller coaster gradually, as does the air that you fly through as you ride the ride.

MORE DETAILS

Roller coasters are driven almost entirely by inertial, gravitational, and centripetal forces. There are three main components to the typical roller coaster: chain lift, catapult-launch lift, and the brakes. The chain lift is the component that pulls all the carts to the “top” of the roller coaster.

MORE DETAILS

The two most important forms for amusement park rides are kinetic energy and potential energy. In the absence of external forces such as air resistance and friction (two of many), the total amount of an object's energy remains constant.

MORE DETAILS

Most roller coasters run by the Law of Inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
