How do roller coasters slow down?

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.

Friction is a force that opposes (goes against or opposite to) the motion of an object. If the roller coaster cars are moving to the east, the force of friction is to the west. The force of friction acts on the moving cars, decreasing the total amount of mechanical energy in the roller coaster.

The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates.

A roller coaster does not have an engine to generate energy. The climb up the first hill is accomplished by a lift or cable that pulls the train up. This builds up a supply of potential energy that will be used to go down the hill as the train is pulled by gravity.

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.

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.

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.

We see that velocity of the roller coaster is independent of its mass and is solely dependent on local g and initial h . Therefore, for an ideal roller coaster an empty roller coaster or a full roller coaster will take the same amount of time for a single trip.

How safe are rides? According to IAAPA, there are 0.9 injuries per million rides and that in a typical year, more than 385 million guests take more than 1.7 billion rides at about 400 North American fixed-site facilities.

This places some limits on the design. For example, the coaster car can't go through a loop or over a hill that is taller than the initial hill because going higher would require more energy than it has available. If the track is too long, friction might eventually cause the coaster car to come to a complete stop.

A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track.

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.

MORE DETAILS

On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion.

The Steel Dragon 2000 is the longest roller coaster in the world, measuring a whopping 8,133 feet in length.

An on-ride camera is a camera mounted alongside the track of a roller coaster, log flume or other thrill ride that automatically photographs all of the riders on each passing vehicle.

However, people are actually more likely to be killed on the car ride to amusement parks than on the rides in amusement parks. As we talked about in class, car crashes kill 40,000 each year, which means around 100 everyday.

People with high blood pressure and/or heart conditions are warned not to ride roller coasters because of the way they tax the cardiovascular system. The adrenaline rush that roller coasters give you causes a rapid spike in your heart rate and blood pressure.
