Vocal Music.A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopesand sometimes inversions.
Most roller coasters have multiple cars in which passengers sit and are restrained. Some roller coasters, notably Wild Mouse roller coastersrun with single cars. The oldest roller coasters are believed to have originated from the so-called " Russian Mountains ", specially constructed hills of ice located in the area that is now Saint Petersburg, Russia. Later, inCatherine the Great is said to have constructed a sledding hill in the gardens of her palace at Oranienbaum in St.
However, during the Belle Epoque they returned to fashion. Railway companies used similar tracks to provide amusement on days when ridership was low. Bythe first underfriction roller coaster had been developed by John Miller. Perhaps the best known historical roller coaster, Cyclonewas opened at Coney Island in The Great Depression marked the end of the golden age of roller coasters, and theme parks, in general, went into decline. This lasted until when the instant success of The Racer at Kings Island began a roller coaster renaissance which has continued to this day.
InDisneyland introduced a design breakthrough with Matterhorn Bobsledsthe first roller coaster to use a tubular steel track. Unlike wooden coaster rails, tubular steel can be bent in any direction, allowing designers to incorporate loops, corkscrews, and many other maneuvers into their designs.
Most modern roller coasters are made of steel, although wooden coasters and hybrids are still being built. There are several explanations of the name roller coaster. It is said to have originated from an early American design where slides or ramps were fitted with rollers over which a sled would coast.
Another explanation is that it originated from a ride located in a roller skating rink in HaverhillMassachusetts in A toboggan -like sled was raised to the top of a track which consisted of hundreds of rollers. This Roller Toboggan then took off down gently rolling hills to the floor.
The inventors of this ride, Stephen E. Jackman and Byron B. Floyd, claim that they were the first to use the term "roller coaster". The term jet coaster is used for roller coasters in Japan, where such amusement park rides are very popular.
In many languages, the name refers to "Russian mountains". Contrastingly, in Russian, they are called "American mountains". In the Scandinavian languagesthe roller coaster is referred as "mountain-and-valley railway". German knows the word "Achterbahn", stemming from "FigurBahn", like Dutch "Achtbaan", relating to the form of the number 8 "acht" in German and also Dutch.
Roller coaster trains are not typically powered. Most are pulled up a lift hill by a chain or cable and released downhill.
The potential energy accumulated by the rise in height is transferred to kinetic energywhich is then converted back into potential energy as the train rises up the next hill. Changes in elevation become smaller throughout the track's course, as some mechanical energy is lost to friction. A properly-designed, outdoor track will result in a train having enough kinetic energy to complete the entire course under a variety of stressful weather conditions.
Not all coasters feature a lift hill, however.Doing a roller coasters 2020 homework
A train may also be set into motion by a launch mechanism such as a flywheel, linear induction motor LIMlinear synchronous motor LSMhydraulic launch, or drive tire. Some launched roller coasters are capable of reaching greater speeds using less track when compared to traditional coasters that rely on a conventional lift hill.
A brake run at the end of the circuit is the most common method of stopping a roller coaster train as it returns to the station.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.

Passengers ride in cars that are connected to form a train. The train moves through sharp curves and sudden changes of speed and direction. On most roller coasters, riders remain seated beneath a safety bar. However, variations include riders standing on a platform or being confined with over-the-shoulder restraints.
Roller coasters are found mostly in amusement parks. Roller coaster trains do not have an engine.Reading skills dissertations
Instead, gravity and inertia work together to keep the cars moving along the track. Gravity is the pulling force between objects. Inertia keeps the train moving in the same direction at the same speed until another force changes it. The train needs some kind of boost to get started.
In many roller coasters, a motorized chain or chains brings the train to the top of a large hill. This action builds potential stored energy. The higher the hill, the greater potential for a faster, longer descent due to gravity.
Gravity pulls the train down the hill, and the potential energy is converted into kinetic motion energy. Upon ascending other, smaller hills, the train gains more potential energy, only to release it as kinetic energy on the decline. In vertical loops, inertia keeps the train moving on the tracks despite the pull of gravity.
In the late 20th and early 21st centuries, advances in technology allowed engineers to develop new methods for starting the train. One such method involves a row of electromagnets. Each magnet placed along the tracks attracted the magnet on the bottom of the train. Thus the train was pulled forward. Other roller coasters used a burst of compressed air to propel the train. Such methods create a large burst of kinetic energy in a short amount of time.
The train loses potential energy as it travels along the track. This happens through such occurrences as the friction of the wheels on the track and air resistance. Once the potential energy is gone, it cannot be replaced. This energy loss is what causes the train to slow down at the end of the roller coaster course. In addition, automatic brakes help to bring the train to a stop. The origins of the roller coaster may lie with a Russian sledding ride of the 15th century.
People climbed stairs about 70 feet 21 meters high to an ice-block sled with a straw seat. The ride reached speeds of 50 miles 80 kilometers per hour.The coup that crushed democracy in chile
In a ride based on this Russian one opened in Paris, France. It was called the Russian Mountains. Small wheels were added to those sleds, persuading some historians to credit it as the first wheeled coaster. These rides added locking wheels and continuous tracks. Eventually they used cables that hoisted the cars to the top of the hill.
The railway was built to haul coal on a 9-mile Coal was hauled in the morning, but passengers began to pay 50 cents to ride the train during the afternoon run. In workers opened a tunnel that became the main coal route. However, the Mauch Chunk Switchback continued as a thrill ride.Designing a roller coaster requires careful consideration of several physics concepts.
Roller Coaster Games
Most notably, mechanical energy must be kept track of to ensure the Roller Coaster completes the course. Friction is also an important consideration, however it is rather complicated to deal with exactly.
A simple but poor approximation can be made by assuming a constant drag force resulting in a constant energy dissipation per unit track length. This is not very accurate as shall be seen later, but it is better than ignoring friction all together. Another important design consideration is the accelerations experienced by the passengers.
The goal here is to maximze the excitement of the ride without actually endangering the passengers. By comparison, people can withstand accelerations on the order of 10 g in directions perpendicular to their bodies without any permanent adverse effects, however most Roller Coaster cars would jump their tracks at such extreme accelerations. You may include more features in your roller coaster if you wish. Begin your roller coaster design by choosing the ordering of the features and use your experience with roller coasters to make some rough estimates of the dimensions of the features.
On graph paper, make a scaled drawing of the track from the side in such a way that if you connected the left side of the paper to the right to make a cylinder, you would have a reasonable three dimensional picture of the track. In other words, even though the track makes a large loop in reality, draw it as if the train started on one end of the paper and ended on the other. Note that you will need to take special care at the horizontal loop s to be sure the length of track proposed is sufficient for the size loop s you intend.
Use this drawing to calculate the total length of the track for your roller coaster. Assuming it consists of five cars with a capacity of four people per car, estimate the total mass of the train and its length. The first check is to make sure that the train has enough energy to reach the end of the track. The Roller Coaster is powered entirely by the gravitational potential energy it receives in being pulled to the top of the first hill. For this reason, a good first check of the Roller Coaster is to make sure that the first hill is the tallest feature on the ride.
If this is not the case on your drawing, choose dimensions that fix it, but do not draw a new picture yet. As a lower limit on this frictional energy loss let's consider one of the tallest and fastest roller coasters in the world.
It has a height of This speed is reached at the bottom of the first hill which has a slope of Comparing its actual speed at the bottom of this hill to that achieved in the frictionless case, estimate the average energy dissipated per meter of track going down this hill.
Take this to ba a reasonable minimum rate of energy dissipation. For this to be the case, the ride will have to dissipate enough energy for the final speed to be about five meters per second.
Use this final speed, the height of your track's first hill, and the total length of your track to estimate a maximum rate of dissipation. Use the two rates you have calculated to make a reasonable estimate of the rate of dissipation for your roller coaster. Measure the amount of track the train has to travel over to reach each of those points. From these data, calculate the amount of energy the train has at each of these points.That's why, if these allegations are proven, these guys should be thrown out of the game.
I don't see how you cannot impose the harshest penalty, to send a clear signal. If you don't do that you are saying that crime pays.
Warm welcome: Protesting fans awaiting the return of disgraced skipper Salman ButtThey have until Thursday to respond to the charges laid by the ICC and the indefinite suspension pending an inquiry. Prior to the start of the T20 and one-day series against Pakistan, which continues at Headingley today with England 1-0 up, the ECB made it clear they would not be happy to play against players under police investigation.
But they resolved not to make further protest about the presence of Wahib or Kamran Akmal, deciding instead to get through the remaining matches as quickly and quietly as possible. Meanwhile, England's Jonathan Trott denied he used the allegations to get under the skin of Kamran Akmal during an on-field spat in the first ODI in Durham, which caused umpire Billy Doctrove to intervene.
Trott yesterday played down the incident which left Akmal furious, saying: 'I said a few words, and he was saying a few - and the umpires got in the middle of it and made a mountain out of a molehill really.
