Roller Coasters

80.34 mph

The Kingda Ka at Six Flags Great Adventure in Jackson Township, New Jersey, USA. At its opening on May 21, 2005, it became the tallest and fastest roller coaster in the world, claiming the title from Top Thrill Dragster at Cedar Point. The train is launched by a hydraulic launch mechanism to 128 miles per hour (206 km/h) in 3.5 seconds.

This is an impossible question to answer, as it is too difficult to know how many people ride them every year. There are millions of riders, and perhaps a handful of deaths...most people killed after maintenance workers, not riders. The percentage will be les than 0.000001% if you're using this figure to work out whether you are going to die next time you ride a roller coaster, don't bother. You won't. It's near to impossible.

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.

The main energy transfer is when GPE (gravitational potential energy) gets turned into KE (kinetic energy) this happens when the roller coaster car reaches the highest point of the ride and goes down, thus turning GPE into KE at the bottom. After this initial drop, the rest of the drops have to get lower and lower because of the loss of energy.

A couple months ago I went on my first roller coaster, so I know how scary it can be! I would recommend always going with a friend or family member who can ride with you. It helps to ask them questions about the ride if they've been on it before, so you can know more about it. Before you go on a ride, tell yourself it's gonna be okay! You'll have a blast when you're done, trust me. When I got off my first roller coaster I asked myself, 'why was I so scared'? Also, here's what I've heard about why people are scared to go on roller coasters: Your mind is telling you that going so fast and upside down would normally hurt you, so it makes you feel like its dangerous so you wont want to go on it. But if you can look past that fear and realize it's NOT dangerous, it's totally fun!

they hug the rails

HELP ive got a HUGE science taske about rollercoasters and its really hard!

the gravity will pull the roller coaster down a little bit and then it might go a little slower.

It has changed over time because roller coasters today are muchbigger and faster than before.

As far as launched coasters go, there are typically fins on the side of the coaster car. These fins pass through slits on the side of the track that have a magnetic field in them. The magnetic push or pull is what causes the train to move.

Wooden roller coasters give people such palm-sweating thrills because they have lots of quick swift drops and crazy turns. Of that adrenaline junkies can't get enough of. However, steel roller coasters may have the advantage of being able to be manipulated to loop and corkscrew.

No, it even states on the attention board by the entrance to any rollercoaster that it is very unsafe for anyone with blood pressure or heart conditions.

Tl;dr: No, you'll most likely suffer from a stroke.

The Hulk has a top speed of 67 mph.

Gravity affect people on 6 axis. They are positive or negative x (lateral G's), positive or negative y (vertical G's), and positive or negative z (acceleration G's). Vertical G's When on a traditional coaster (rider is sitting in an upright facing forwards), vertical G's act on the rider up and down. When vertical G's are positive, they make the rider feel like he/she is being pushed into his/her seat. When negative vertical G's are present, they make the rider feel weightless, or even give people that "Stomach in your throat" feeling. Lateral G's When on a traditional coaster (rider is sitting in an upright position facing forwards), lateral G's act on the rider left and right. Positive lateral G's make the rider feel like he/she is being pushed to the right, and negative lateral G's make the rider feel like he/she is being pushed to the left. Acceleration G's When on a traditional coaster (rider is sitting in an upright position facing forwards), acceleration G's act on the rider forward and backwards. Positive acceleration G's make the rider feel like he/she is being pushed forwards (like quickly speeding up in a car; mainly felt on roller coasters with launches). Negative acceleration G's make the rider feel like he/she is being pulled backwards (mainly felt on the brakes of a roller coaster when decelerating)

The roller coaster was invented by Granville T. Woods and the first one was made of wood because his last name was wood.
The first roller coasters were made of wood. They were planks of wood attached to a short 1 metre chain lift in the centre. This was made of metal. By the way, if you didn't know, the first rollercoasters were made in the 1860's although these were controlled by only humans on their hands and knees working pulling ropes the make the car run. The first rollercoaster tracks were made of wood and sometimes metal.

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.

Roller Coasters originated from ice slides that were built in Russia in the 1400's.

On a roller coaster, we see the cars lifted to the high point on the ride. This converts the kinetic energy used to lift the cars into potential energy. When the cars are dumped over that initial apex, the potential energy is converted back into kinetic energy. As those cars continue along the track, conversions of kinetic energy to potential energy will occur at each rise along the course, and there will be conversions from potential energy back into kinetic energy at the drops. This continues until the end of the ride, where most of the potential energy that was initially put in has been lost in friction, and only a bit of braking is needed to stop the cars.

The fastest roller coaster in the world is at Six Flags in Jackson, New Jersey. It is named Kingda Ka. It is 456 feet tall and runs 128 mph.

When you see a roller coaster you have probably noticed that the first hill of the roller is always the highest unless it has given potential energy. Potential energy is force or stored energy. This is happens because not all potential energy is converted into kinetic energy. Kinetic energy is the energy of motion.
