centrifical force
the two forces are friction and gravity
it's periodic motion.
Well, to understand what a roller coaster does you will need to understand what a roller coaster is. A roller coaster is a small vehicle that runs along a fixed track. What a roller coaster does is move along that fixed track at very high speeds, and many people find this very thrilling And if your wondering how a roller coaster works 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. For info on the launched roller coaster check out the related links.
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
A Roller Coaster is a large and massive ride in theme parks. Though names and types of ride may be similar in Six Flags Parks they do not share the exact same coaster.
It provides undesired slowing of the coaster on its path but it is essential for the brakes to stop it at the station.
There are several types of Roller coaster brakes, most of them look loosly similar . The exception is the ratchet brake that goes "Clack Clack as you go up the lift hill. The next several types look like a metal fin that stick out the side or bottom. The friction brake rubs a brake onto this fin as the car goes through. Common on old school wooden coasters. The Linier induction brake, esentially the brake "Fin" goes between a bunch of electro magnets that are computer operated to either speed up or slow down the coaster. The neatest kind is an Aluminum Fin on the car that runs through a series magnets and through a weird interaction between the Aluminum and Magnet the car slows down. If you vary the strength of an Electro Magnet you can increase or decrease the effect.
Most roller coasters will accelerate due to gravitational potential energy being converted to kinetic energy on the coaster car after being gained from a hill lift. There is no way of controlling the acceleration due to it completely being acted upon by gravity. Different types of track; car design and wheel bearing will affect the acceleration slightly.
Some one with high blood pressure should not ride roller coasters because they put several different types of stress on the body which can cause your blood pressure go up even higher and put your heart in danger.
Bumper Cars is fun!
"Types of roller shutters include: built-on roller shutter doors, integrated roller shutter, roller shutter with tilting laths, manual, manual tape, electric, and fire shutter."
The vast majority of complex structures/designs use more than one area of technology. Perhaps the most important one is actually computer technology, as computers are an important active safety feature for roller coaster operations and are vital in designing the actual roller coaster. Computer simulations are able to realtively-easily calculate the advanced physics (stresses, curves, air resistence and other factors) that are required to make the design work as safely as possible. With better computer design tools, more radical designs are able to be built. Another major area of technology is materials science. The availability of materials fitting specific needs can be a major factor limiting the capabilities of a roller coaster or any design in general. There are of course many other types of technology such as manufacturing technology that are related to the coaster
