Roller Coasters

Road Wheels-these run on top of the track.

Friction Wheels-these either run on the inside or outside of the track, depending on the builder. They are used to make sure the car doesn't go off the side.

Upstop Wheels- these are on the bottom of the track so that when the car gets airtime or goes through an inversion, the car stays on the track.

The height of hills affect the roller coaster by the amount of gravitational potential energy that is collected while rising. The more GPE you amass as you ascend, the more kinetic energy is affected. GPE=(mass)(9.81m/s2)(height). Therefore, the higher the hill, the greater the potential energy. The greater the GPE, the more speed (Kinetic Energy) is able to be used.

Velocity is constant when the middle of the roller coaster is parallel with the ground (when the tangent of the curve the roller coaster is on has a slope of 0 at the center of mass of the roller coaster).

to be honest with you, the only scary thing about the dragster is the thought of it while waiting in line, because you're thinking about it which makes you nervous. as soon as you launch off that ride you have no time to be nervous anymore because it happens too fast. it's approximately 30 seconds long, if it doesn't stall, meaning you don't make it all the way up the hill and it goes back to the beginning (which is a rare chance it will) if it does stall you get the amazing gift of getting to go again!

Suppose you serve water to some which is cold and having ice cubes in it. After sometime, water drops will beginning to appear on the outer surface of the glass. They will now become sweaty and will do wet the table, floor or any place where you put it. Does it looks good in front of guests? Why don't you use some thing which is made for this purpose?

The basic object of a coaster is to keep the moisture away from all the surfaces in your home. They work in two ways by holding the liquid on the surface of the coaster, or by observing the moisture into the coaster itself.

It starts quite slow then when the lights go to 'green' your off!. That bit goes at 70mph approx but slows down a little. Has one upside down and bends. You can take bags on with you as the g-force keeps them down just hook them on your leg maybe.

Newton's first law of motion states that an object in motion tends to stay in motion. This is what keeps the roller coaster rolling through the hills and turns after it accelerates down the initial ramp. Also, the riders inside the car will experience changes in accleration and apparent weight. The riders will keep going at the same speed in the same direction unless some other force (the seat) acts on them to change that speed or direction. At the bottom of hills, they try to continue downward, and are pressed into the seat. At the tops, the riders are lifted up in their seats as they try to continue upward even as the seat pulls them down into the next drop. The same thing occurs on turns, where riders are pushed into the side of the seat as the coaster turns. (This is the reason for harnesses, seat belts, and restraining bars.)

the griffon is 205 ft with a 90 degree angle drop

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.

It varys during the day but it is usually 1 in a half to two hours

16 roller coasters are in Florida.

Everyone loves florida.

its so bright, and sunny! yum

what is the simile riding a rollercoaster and flying

Yes it can. Sudden jolts and jerks on a roller coaster rides and even bungee jumping can cause laceration and tears in the liver and spleen leading to internal bleeding. Retinal detachment can also occur in bungee jumping.

By far the best kit on the market is to be found at www.paperrollercoasters.com The cost is only $20, and you simply buy heavy paper, scotch tape, scissors and markers on your own (I usually visit the dollar store for many of these items!)

The first roller coaster that was made in Hershey Park was The Comet. The Comet was opened up for the first time in 1946.

The first roller coaster was Switchback Railway, opened in 1884, going only 6 mph.

The Top Thrill Dragster was built 2 years ago ( 2008 ) at Cedar Point. Cedar Point was built in 1970. The oldest roller coaster at Cedar Point is the Mine Ride.

There are actually 3 simple machines in Roller Coasters. A wheel an axle is what the carts use to go along the tracks, the chain that pulls the cart up the hill counts as a pulley and the whole ride is just filled with inclined planes

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.

They wanted to make new kinds of roller coasters just like they wanted to make them higher.

There is the Incredible Hulk, the Dragon Challenge, and Pteradon Flyers.

The momentum from the drop makes the coaster go for nearly the whole ride.
