The beginning of rollercoasters dates back to the 15th century in Russia, where the first coaster ride was simply created in the form of an ice slide. During the 1400’s, long and steep wooden structures were built to heights of 70 to 80 feet tall with ice frozen over the long and sloping ramp, see Figure 1 (Learner.org, 2016). Sledders would be mounted on an ice or wooden sled down a 50o drop platform with little support at tremendous speed. Ice slides were built parallel to each other, however facing opposite direction, allowing riders to travel back and forth (Learner.org, 2016). In 1817, wheeled cars which securely lock onto the track were introduced to the early development of rollercoasters and the first complete circuit was built in France (Learner.org, 2016).
By 1980, modern innovations and coaster dynamics introduced the concepts of hills and dips, vertical loops, banked curves and inversions to modern coaster rides. The development of steel-railed tracks was introduced in America which soon led to further innovations including the Formula Rossa in Abu Dhabi, the world’s highest and fastest rollercoaster to be invented which reaches a top speed of 149.1 miles per hour (Wonderopolis.org, 2016).
Rollercoasters are not powered by machines, however, it is simply driven by basic inertial, gravitational and centripetal forces (Teachengineering.org, 2016). A rollercoaster ride is a balance between health and safety factors, thrill and sensation. The thrill of a rollercoaster arises from the physical principle of the ride, the law of energy conservation. The key to a successful coaster stems from the basic motion concepts including velocity, potential and kinetic energy, centripetal forces and...

...ters the loop to loop, Centripetal Force (Fc) starts to act upon the rider in order to keep the coaster train travelling throughout the loop to loop. It is the total force of inertia, the upward force known as the “apparent” weight (Fs) exerted by the coaster train, the downward pull of gravity (Fg) and centripetal acceleration (Ac) which acts on the coaster train as it travels through the vertical circle, refer to Figure 2.
Centripetal Force is regard as:
Where m = mass, v = velocity and r = radius of the vertical loop. The required minimal centripetal force to the coaster train at the top of the loop was calculated to be 42 673.5 N acting upon the coaster train. However, at the top of the loop, gravity reduces the veocity and as a result, KE is converted into GPE. As it speeds around the top of the loop, it is travelling at a minimum speed of 15 ms-1.

- The Physics of Roller Coasters The roller coaster has its beginnings in Russia where during the 1600's. People crafted sleds out of wood and built hills made of ice blocks. The hills had sand at the bottom to help slow down the sleds so they would not crash when they reached the bottom of the hill.1 Over time, the roller coaster has become more complex. They now are taller, faster and are designed out of different materials like wood and steel. Although roller coasters are fun and exciting, the questions, what allows them to twist and turn, go up and down hills at a fairly good speed.... [tags: Physics Science Research]

- Roller coasters are driven almost entirely by inertial, gravitational and centripetal forces. Amusement parks keep building faster and more complex roller coasters, but the fundamental principles at work remain the same. A roller coaster is like train. It consists of a series of connected cars that move on tracks. But unlike a passenger train, a roller coaster has no engine or power source of its own. For most of the ride, a roller coaster is moved only by the forces of inertia and gravity.... [tags: Roller Coaster Theme Park Amusement]

- ... But thankfully engineers were able to create a new design for the loop. This clothoid shape, or tear drop shaped loop, (See Appendix C) allows the train to safely invert riders. The key to the clothoid shape is the loop’s changing radius; “which controls the speed of the cars, varying it according to a scientific law known as the conservation of angular momentum.”(Claiborne) Stretching the circle into a teardrop shape allows multiple radii lengths throughout the loop. A large radius at the bottom of the loop allows the train to enter the loop slower and lessen the centrifugal force on riders.... [tags: closed circuit, potencial and kinetic energy]

- The very first “roller coasters” were created in Russia in the 1600’s, and were nothing like the typical roller coaster that comes to mind today. People rode down steep ice slides on large sleds made from either wood or ice that were slowed with sand at the end of the ride. These sleds required skill to navigate down the slides, and accidents were frequent. A Frenchman tried to cash in on the popularity of the Russian ice slides by building one in France, but the warm climate quickly ended his attempts with ice....

- Did you know that almost all roller coasters only rely on Earth’s gravity to get the cars down the track. Roller coasters are centered all on physics and I will hopefully teach you some things, big or small about them today. In this essay we will be exploring the world of roller coasters. Some of the topics we will cover will range from the history, to the principles that allow the cars to continue throughout the length of the track, and the general physics surrounding roller coasters. The history of roller coasters is a really cool one if you ask me.... [tags: Roller coaster, Steel roller coaster]

- Roller Coasters Roller coasters have come to be one of American’s favorite pastimes. Amusement parks are more popular than ever thanks to the exciting, fast-pace, “scream machine” rides known as roller coasters. Though many people may not know, roller coasters are entirely based upon science, from the speed of the cars to the safety of the ride. For one to understand the thrills as well as fears one experiences on a roller coaster, one must first understand the most basic component of these rides, the physics.... [tags: Roller Coasters]

You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart....

- People sometimes say that life is like a roller coaster, well that is kind of true because just like a rolling coaster life has its ups and downs and the thrill of being high above and the fear of fall down from the top. Roller coasters can give you a feeling like no other feeling in this world. While roller coasters gives the so much to the people there are bunch of physics that is involved in the making of roller coasters. Without physics and newton’s laws it will be very hard to make roller coaster since every loop or and drop replies forces and how much energy is distributed....

- Undoubtedly roller coasters are the kings of amusements parks. Whether you enjoy a older, rickety wooden roller coaster with its thrill of positive and negative G's and a fairly wobbly feeling. Or, you prepher something newer, a tube steel roller coaster. A coaster that is faster, one that includes death defying speeds, hairpin turns, and of course the cr�me de la cr�me, loop de loops. However, regardless of you personal tastes and preferences, through exploring this page you will find that all roller coasters are indeed bound by the same fundamental laws....
