How do roller coasters work?

Answer 1

The chain lift at the beginning part of the ride lifts it up over the edge. Then with speed the train is basically on it's own. Not all Roller Coasters run on chain lifts. Some get launched like a sling shot such as Top Thrill dragster at Cedar Point. Some get lifted with an elevator like Millennium Force also at Cedar Point.
The roller coaster slows down with a magnetic part of the track. So that's mainly how roller coasters really work.

they use gravity=)

Answer 2

A roller coaster is a dynamic, three dimensional fixed course, gravity operated recreational vehicle. We build a track. We have included in our track design some curves and loops to increase the level of enjoyment. (Call it the fun factor.) We figure out how to make some cars that will roll along the track. Not too tough, but critical for safety. We put a short string of cars together, fill them with folks and send them on their way. At the beginning of coaster rides is a big long "hill" to climb. The cars are cranked up to the top, and through all the time they are being lifted, energy is being added. This energy collects in the cars (and riders) as they are lifted to the highest point of the track: the start. Special note here: all the energy that is used in the ride has been put in by lifting the cars up the starting grade. All of it. Gravity has been acting on the cars all the time. By lifting the cars, the energy of gravity (that constant pull) has been "overridden" by our lifting machinery, and now we are about to tap that energy. With a nudge, the cars go forward and start down the initial descent. Gravity pulls the cars down, and we're flying! We are now converting the stored (potential) energy we gathered climbing the hill at the start into the energy of motion (kinetic energy). In the turns and loops, the cars careen around and we are pressed into the seats. We change the course of the track and reorient the cars along the way to make it more fun and redirect energy. As we make those twists and loops, we will be tapping more of that energy that we stored in the cars at the start, and we'll be using it to keep the cars on the track in the loops and twists. We finally come to a stop. End of the ride. Exit safely, please. Come back again soon. By the way, is there any place on a roller coaster that is higher than the starting hill? That one we had to be cranked up to the top of at the beginning of the ride?

Answer 3

Most roller coaster, like railroad trains, are pushed my electric currents from the tracks to the wheels giving a constant speed or bursts for more trilling or intense rides. Others are climbed to certain heights on the tracks with an engine-powered belt hooked to the bottom of the carts. Then the carts are released from those heights and are expected to circulated trough the whole course.

Answer 4

Well, there are 2 types of roller coaster, most commonly the Chain Lift, The chain lift works by hooks on the bottom of the roller coaster car that hook on to a roller chain (the type of chain you would find on a bicycle) and the chain pulls you all the way to the top of the big hill, This is the part where you hear all the clicking. As you start going down the big hill the hooks simply slide out of the chain and gravity starts to take over, but the roller coaster can stay moving because of Kinetic energy and Potential energy. So the 3 things that are very important to a Roller Coaster are Kinetic energy, Potential energy, and gravity. A roller coaster works sort of like rolling a ball down a hill.

Answer 5

The simplist answer is gravity, with the cars being guided by rails

Answer 6

Roller coasters move throughout a ride by being pulled or pushed along by a cable or pole.
