Roller Coasters

uase it just does. The cars move. Motion of material things IS kinetic energy.

Things like descending a very tall hill or turns affect the speed of a roller coaster. Riding down the hills increases speed, and turns slow the coaster down.

Mechanical Energy encompasses both Kinetic and Potential energies. A roller coaster is a perfect example of both. At the very top of a hill, the roller coaster has a lot of potential energy due to position above the earth. As it goes down a hill, this potential energy decreases as it gets closer to the earth, and it's kinetic energy increases as it gets faster.

KE = energy of motion

PE = potential energy due to position above the earth

ME = KE+PE

Granville T. Woods invented the roller coaster after he stole the idea from Abraham Lincoln in 1877. This was during the mesozoic era so the mostly dinosaurs went on them. It was more frequent for a Tyranosaurs rex (t-rex) to ride a roller coaster than a triceratops

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.

No, Cedar Point will not be making a new roller coaster in 2011. They will be making a thrill ride called the Windseeker which is not a roller coaster. If you meant later in the future, nobody knows but the park officials.

A roller coaster is called des montagnes russes (always plural), which literally means "Russian mountains". According to Wikipedia, the reason is that the idea for the first roller coasters was based on sled rides on snowy hills in St. Petersburg.

A modern steel roller coaster with loops and/or other "extreme" elements can be called un grand huit or un manège grand huit.

It entirely depends upon the size of the roller-coaster, and the number of cars it has. There is no standard number- some carry as little as 12 people, others can carry 40 or even more.

It's entirely down to safety factors which are determined by the length of the ride, and the nature of it, i.e. whether it's just a simple 'big dipper' style one that goes up and down a curved track, or whether it's one of the more modern 'extreme' rides that corkscrew, plunge down vertically, loop the loop and so on.

The Son Of Beast in kingsisland went upside down but they had to get lighter trains and in order to have the loop they needed heavy trains Son Of Beast is no longer open in kingsisland.

not just seat belts. Harnesses, which are much more secure. There are lap bars, which on some coasters, like intimidator 305 in kings island VA, really hurt. There are also over-the shoulder bars which are on coasters like bizarro at Six flags great adventure

On a coaster g-forces constantly push and pull at our bodies. If we go fast enough, the force of gravity can stop the flow of blood to our brains and eyes, causing blackouts or temporary blindness.

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!

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.
