Centripetal force might work. When a roller-coaster train goes around a loop, centripetal force keeps it from falling down, and propels it outward. Well, that and some extra wheels, but you know what I mean.
In the last few sections, we looked at the forces and machinery that send roller coasters rocketing around elaborate courses. As you move over the hills, valleys and loops of the track, the forces on you seem to change constantly, pulling you in all directions. But why is this rollicking movement so enjoyable (or, for some people, so nauseating)?
To understand the sensations you feel in a roller coaster, let's look at the basic forces at work on your body. Wherever you are on Earth, gravity is pulling you down toward the ground. But the force you actually notice isn't this downward pull -- it's the upward pressure of the ground underneath you. The ground stops your descent to the center of the planet. It pushes up on your feet, which push up on the bones in your legs, which push up on your rib cage and so on. This is the feeling of weight. At every point on a roller-coaster ride, gravity is pulling you straight down.
The other force acting on you is acceleration. When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity. But as the car speeds up or slows down, you feel pressed against your seat or the restraining bar.
You feel this force because your inertia is separate from that of the coaster car. When you ride a roller coaster, all of the forces we've discussed are acting on your body in different ways.
Newton's first law of motion states that an object in motion tends to stay in motion. That is, your body will keep going at the same speed in the same direction unless some other force acts on you to change that speed or direction. When the coaster speeds up, the seat in the cart pushes you forward, accelerating your motion. When the cart slows down, your body naturally wants to keep going at its original speed. The harness in front of you accelerates your body backward, slowing you down.

How do roller coaster go fast?
Roller Coasters go fast because they use gravity to their advantage. Because the cars weigh a lot, they fall at very high speeds from high in the air. Some of the new roller coasters being built also are propelled forward using the force created by high powered magnets.
How can roller coasters use fossil fuels?
Most, if not all, roller coasters are powered by electricity. Most electricity is still being generated by burning of fossil fuels (coal, oil and natural gas). As this burning emits carbon dioxide you can clearly say that roller coasters are contributing to global warming by using fossil fuels.
How do roller coasters go so fast?
Roller coasters go fast because they use gravity to their advantage. Because the cars weigh a lot, they fall at very high speeds from high in the air. Some of the new roller coasters being built also are propelled forward using the force created by high powered magnets.
What three forces drive a roller coaster?
A 3 wheel locking system, it works by one wheel on top of the rail, one wheel on the side, this wheel helps it go around curves, and 1 wheel on the bottom of the rail, these are called up-stop wheels that prevent the roller coaster from flying off the tracks. This 3 wheel locking system sort of hug the rails to lock the roller coaster train to the rails.
When do riders free-fall on a roller coaster?
Well in roller coasters there is potential and kinetic energy. So when the roller coaster is getting pulled up it is using kinetic energy while gaining potential energy. So the potential energy it gained is used while going down and not being pulled.
How does the law of conservation-of energy relate to roller coasters?
It is easier to see this using a traditional roller coaster model. Most traditional Roller Coasters start by using a tow cable to pull them up a large "hill". When being pulled up this hill, mechanical energy is being used to give the roller coaster potential energy. At the top of this hill, the roller coaster has it's maximum potential energy. As it starts to go down another hill, it picks up speed. During the descent it is losing potential energy but at the same time gaining kinetic energy. The coaster will then lose kinetic energy but gain potential energy as it goes up the next hill. This cycle of gaining/losing potential and kinetic energy is the conservation of energy that you are looking for. Of course in a real roller coaster, some energy will be lost due to friction. This will come off as heat in the rails and the wheels of the roller coaster and it's structure.
How can I create DIY coasters using wood?
To create DIY coasters using wood, you will need to gather wood slices or squares, sandpaper to smooth the edges, and a sealant to protect the wood. Sand the edges of the wood to make them smooth, then apply the sealant to protect the wood from moisture. Let the sealant dry completely before using the coasters. You can also add decorative elements like paint or designs to personalize your coasters.
How do breaks work on an roller coaster?
The brakes are basically 2 pieces of steel and then they close together to a certain thickness. There is also a fin on the bottom of the car which, when it tries to pass through that thin brake, it slows down or even stops the car.
How can I create unique coasters using wood as the main material?
To create unique coasters using wood as the main material, you can start by selecting a type of wood that appeals to you, such as oak or maple. Next, cut the wood into square or round shapes of your desired size. Then, you can personalize the coasters by adding designs or patterns using wood burning tools, paint, or stains. Finally, seal the coasters with a protective finish to make them durable and water-resistant.
What are the different ceiling texture roller patterns that can be achieved using a ceiling texture roller?
Different ceiling texture roller patterns that can be achieved using a ceiling texture roller include stipple, swirl, popcorn, and knockdown.
How can I make coasters using different materials and techniques?
To make coasters using different materials and techniques, you can start by choosing a base material such as cork, ceramic, wood, or resin. Then, consider different techniques like painting, decoupage, resin pouring, or clay molding to create unique designs on the coasters. Experiment with various combinations of materials and techniques to achieve the desired look and functionality for your coasters.
What is the name for fear of roller coasters?
Well the first thing you should do is ride the kiddie roller coasters first (thunder mountain, space mountain, ect) then work your way up. When youre on an intense coaster and you feel like youre gonna throw up, just scream as loud as you can, it will release some adhrenaline. Also dont close your eyes, that will make the drop worse D: and you should go with a friend whos either been on before or never been on. A good way to prevent feeling sick is to put your feet flat on the ground on the cart and pretend youre using an imaginary steering wheel, "driving" the coaster. This will make you feel like you have Control over the cart and will reduce adrenaline. This will help, but its not recommended for you will most likely get in trouble; on the roller coaster, swear like crazy!! This will reduce alot of adrenaline. Hope this helps! :3
