...In any amusement park, the roller coaster is usually the most popular ride. It was first built in Russia during the 16th century, ever since then, the roller coaster has been a hit. With the car slowly moving up the everlasting height of the hill, high enough to touch the clouds, and then rushing downwards through many loops and twists, is enough to keep one’s adrenaline pumping. But what is the secret of the roller coaster? How is it possible for it to work this way? The answer is science. Many may not know, but science, specifically physics, has a lot to do with roller coasters. The roller coaster is actually powered by many types of energy: mechanical, potential, and kinetic. Mechanical energy is ‘the energy acquired by the objects upon which work is done.’ (Definition of Mechanical Energy). Potential energy is ‘energy possessed by an object because of its height above the ground’ (Definition of Potential Energy). Kinetic energy is ‘the energy of motion’ (Definition of Kinetic Energy)....

...Roller coasters have come a long way from ¨monumental ice slides¨ in the 16th and 17th century to an actual steel cart with wheels today.As we go on we will discuss the history of roller coasters,the physics behind them,and the authors experience in the making of its own roller coaster. The history of a roller coaster goes back a long time to the 16th and 17th century.The first roller coaster started as a ice slides which eventually developed in to rolling carts.Then as time went two of the first roller coasters were created,one being in the Russian MT of Belleville created as ¨a train attached to a track¨ and second the first American made roller coaster which was originally made to send coal but was then remade into a more scenic tour.It was called ¨Mauch Chunk Switchway railway.¨As time went soon the roller coasters were made into wood an so on developed. Roller coaster use two main things in order to finish the ride,known as inertia and gravity.As the roller coaster goes up the track and eventually gets to the peak of the roller coaster gravity soon pulls it down the track it causes the roller coaster to change its energy.The roller coaster soon goes from having potential energy to kinetic.But since...

...ne hot sunny day at Six Flags over Georgia a little boy thought to himself, “how does the roller coaster go up so high?” A worker spots him and go over and asks “hey young man what are you thinking about?” The little boy smiles and asks “how does a roller coaster work?” I grin and say “Well young man you're in luck because today I'm doing a tour,and i will be talking about the physics of roller coasters. Do you want to join?” He jumps and gets excited, “ YES YES!” With that, i gather more kids and begin tour. This roller coaster is called the Loopdy Loop and it is one of the biggest roller coasters in the park. A roller coaster is a machine that uses gravity and inertia to send a train of cars along winding train. This combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track....

...Mathematics in Rollercoasters There are several different types of math used in building and creating roller coasters. Some of them are: angles, heights, velocity, slope, gravity, rotation, and more. Below, I will be explaining some of the equations and mathematical ways of figuring them out. First there are angles, which is “the space measured in degrees between two intersecting lines or surfaces at or close to the point where they meet.” To figure them out, the engineers use machines, models, and test coasters to come up with the perfect angles. They need to make sure the measurements and angles work right before they can go back to designing the actual coaster. Roller-coasters do not have engines, but they are controlled almost completely by the angles and velocity it reaches after the first big drop goes down. Heights are “something figured out by measuring from the base to the top. Specifically, for the roller-coaster, the engineer usually measures the highest point of the coaster, from the ground to the top of it. Next, is speed or velocity, which is “the speed of something in...

...When roller coaster start to elevate up it uses an engine. Once it reaches the top it stops and turns to potential energy, because it is still and getting ready to fall. When the coaster falls it turns into kinetic energy, because it’s in motion. From the on the coaster doesn’t need an engine. The gravity takes it down the coaster in a large amount of speed. Then the speed that can go up to like 60 mph will keep the roller coaster going even if it is going up a hill or down the speed is strong enough to take it all the way. The energy will stay for a while, but roller coasters aren’t too long. You may wonder why roller coasters aren’t too long because the energy will start to fade and the roller coaster will slow down and eventually come to...

Appendix Slowly, and sometimes, ever so slowly, a train of cars are being pulled up to the highest point of the roller coaster. Of course, one by one, the cars are pulled downhill until gravity takes over and push it all across the tracks. The way the roller coaster goes around is one of the best examples of how the conversion of gravitational potential energy to kinetic energy from the highest points. As the cars go up the track, it is acquiring the potential energy until the cars are at the highest point of the track. At this point, the cars have reached its maximum gravitational potential energy. Next as the cars go down the track, the potential energy is then changed to kinetic energy. Eventually the cars go up another hill and some of the kinetic energy is changed again to potential energy. This is the loop of energy conversions that go around dealing with roller coasters. Energy is the ability...

...realizing the scientific nature of physics being involved. Physics exists all around weather one is cognizant or not. For example, roller coasters have become quite the attraction at major theme parks all across the globe and operate due to physics. Many men, women, boys and girls want to experience the thrill of zero gravity, upside down loops, twists and curls at extremely fast speeds. However, there is another portion of the population who does not want to go anywhere and would rather speculate from the ground. In either instance, the detailed study of physical science makes it all possible. Even though the physics of a roller coaster are intricate due to the composition of various forms of energy, accelerometers and gravitational forces; their makeup can be quite intriguing. The study of physics dates back several years and can be attributed to different individuals. Knowing the history of physics will help understand general concepts and how they can be applied to creating objects such as the roller coaster. The lessons initiated from the historical founders of physics are vitally important to apprehend the ideas of today and more importantly the direction for how they will shape tomorrow (Garcia et al., 2010). Copernicus, a prominent attributer, initially suggested that the planets revolve around the sun and the Earth rotates on an axis (Britannica Biographies, 2011). The idea will later assist Galileo, another prominent Physics historian, with theories such as...

...Roller Coasters are not self propelled they are pulled up by a chain or cable along the hill to the first peak of the roller coaster track. When the roller coaster stops it gathers tons of potential energy. When the car races down the track it produces kinetic energy. they also have a lever that lifts the car down the track, but the main thing that helps the car go down the track is Gravity. Gravity is the force that attracts something toward the center of the Earth. The oldest roller coasters originated from Russian, which were constructed out of hills of ice. The drop was 50 feet. Later on Most roller coasters were built with wood. In 1959 the first steel track roller coaster was built at Walt Disney World. A big...

...Roller coasters work by a lot of supports and machinary. Roller coasters also work by tracks, that is what makes a roller coaster what it is. Roller coasters are made for fun and it is hard work to make one. It gets built by good machinary, supports and much more. You need good workers to make a roller coaster or else it will either fall down or the riders will be in huge risk. There is only 1 way to make a roller coaster work and that is for a machine to carry the coaster up and then the rest is up to the inclines and declines in the roller coaster. There is another way and that is rapid changes in the speed and directions that is made. After you are carried up a incline by the machine there can not be big inclines for the rest of the ride or else the coaster can stop in the...

...arithmetic, I do not think any type of math is absolutely mandatory to do mathematical model. The roller coaster problem, for example, could be modeled by using a simple weighted average to calculate a total thrill score based on whatever attributes of the coaster are determined important. The coasters could then be ranked. To make generalizable models that go beyond ranking a known individual items in a sample, an understanding of variables and by extension basic algebra would be needed. Many phenomena that we may want to model involve changes over a period of time. Oftentimes these changes can be best symbolized as rates. In these cases knowledge of calculus and differential equations would be useful....

...Rollercoasters are driven by different forces of gravity, inertia and centripetal. The physics used in a rollercoaster also involves friction, work, air resistance, and energy. It usually begins with a mechanical device i.e. motor and chain; they exert a force on the roller coaster car train to lift them to the top of the hill. From this point, gravity starts operating, and the duration of the ride undergo energy transformation. Pulling the rollercoasters uphill uses energy, this energy does not simply disappear. It is stored this energy just by being up in the air and the higher they have pulled the more energy they store. The stored energy will be used to race back down the hill when the ride begins. This is because they have the potential to use future energy that was stored in the past. The stored energy is called Potential energy. Once the cars are released and start rolling down the hill, the force of gravity makes them hurtle downwards when they round the brow of the first hill. As accelerate and pick up momentum, their potential energy turns into kinetic energy. The further they go downhill, the faster they go and more potential energy is converted into kinetic energy. When the ride starts, the cars have a certain amount of potential energy. They can never have more than this no matter how long the ride will last. Through the whole ride, potential and kinetic energy keep swapping back and forth that’s why rollercoaster cars always go slower in higher bits of the ride...

...Some may be more outgoing, or in some cases, introverted as others, but as a whole humanity has “the most complex social structure on the planet. We gather in families, tribes, clans, nations. We have an incredibly sophisticated method of interacting -- speech. We can communicate over time and distance through printing and broadcasting” (Taflinger 3). Humanity has used these incredible social skills to communicate and work for each other in an ever developing world. Newton’s discovery of gravity and his three laws of motion however, are some of the most important things that run the world. Engineers use the force of gravity to accurately determine the size of structures that need to be built such as bridges, skyscrapers, and roller coasters. The engineers may have to use a distance given to them and their knowledge on how gravity works to construct a bridge that will maintain stability. Engineers must also know that “Gravity loads constant magnitudes and fixed positions that act permanently on the structure” (Structural Loads). These facts were not thought up by Newton himself, as he was not an engineer nor were there metallic bridges during the 18th century, but they were brought upon the world because of what Newton had done. Without the discovery of gravity the world would not be able to use terms such as “Net Force” or use bridges, for they both involve gravity. Other such examples are the space shuttles needing a specific amount of force to lift up of the earth and...
