How do roller coasters go from fast to slow?

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.

The force of gravity will cause it to speed up as it moves down the hill. Because there is no friction between Points A and C, the energy of the rollercoaster remains constant over that portion of the motion.

A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy.

The force of gravity pulling a roller coaster down hill causes the roller coaster to go faster and faster, it is accelerating. The force of gravity causes a roller coaster to go slower and slower when it climbs a hill, the roller coaster is decelerating or going slower.

Basic mathematical subjects such as calculus help determine the height needed to allow the car to get up the next hill, the maximum speed, and the angles of ascent and descent. These calculations also help make sure that the roller coaster is safe. No doubt about it--math keeps you on track.

The best seat on a coaster, then, is a matter of personal taste. If you love the feeling of weightlessness, head for the back. If you want the best view of the action, head for the front. The cars in the middle provide the weakest ride, but it's a good bet you'll still have a good time.

Theme park designer Brian Morrow explained that rollercoasters get faster throughout the day because they need to warm up earlier in the day, like a car. He told Mental Floss: A coaster running in the morning could run slower when cooler. “The wheels are not as warm, the bearings are warming up.

At the bottom of the loop, gravity and the change in direction of the passenger's inertia from a downward vertical direction to one that is horizontal push the passenger into the seat, causing the passenger to once again feel very heavy.

Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water. The water dummies increase the mass of the train making it harder for the resistance forces to slow it down so it's less likely to get stuck.

Different types of brakes are used to stop the train at the end of a ride. These brakes use friction to slow down and stop a roller coaster's momentum by converting the train's kinetic energy into heat energy. For example, roller coasters are kind of like riding your bike down a hill.

In a typical coaster design, the riders in the front car get an unobstructed view of all these obstacles whipping past them. In a coaster that has seats facing backward, the rear car offers the best of both worlds -- you get a great view and the most intense ride.

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.
