Physics of Roller Coasters
We have all gone to an amusement park and saw the insane triple looped, upside down, hanging from your feet roller coasters, zooming feet above our heads. But realistically, how is this possible?
Roller coasters all begin with some initial boost to initiate momentum and speed. In most cases, this boost, otherwise known as a “lift hill” or “chain lift”, mechanically pulls the roller coaster to the top of the first, and tallest hill. Other roller coasters use a Hydraulic Launch System to shoot the coaster straight into its fast speed. Hydraulics uses a system of two cables that connect to the bottom of the roller coaster’s catch car, the bottom of the car, and a winch that will pull the cables and release the car at

The law on conservation states that the total energy in one part of the coaster will be equal to any given part of the coaster. Total energy is equal to the sum of the potential and kinetic energy.
In order to keep the roller coaster from crashing into the ground, it needs a buffer to slow it down. Loops are one of the ways that this can be done. Depending on how high the hill is, your loop will be larger or smaller. If the hill adjacent to the loop is taller, then the loop will be larger. Looping also requires a centripetal force, the force that acts on a moving object going in a circular path. Centripetal force is based off of the weight, velocity, and radius of the loop.
However, a loop for a roller coaster is not a circle, called a vertical loop, rather it is a teardrop shape. It has been discovered over the years that having a more circular loop can cause severe neck and head injuries because of the intense force from the radius of the loop. Loops are nowadays formed into a clothoid loop to ensure safety and reduce pressure. While going up the loop, the car is acting against gravity, making it move slower as it gets to the top of the loop. Once the car has passed the middle it begins to move faster with the help of gravity. If the loop curvature is constant than it will emit the greatest force at the end of the loop. If the curvature of the loop is not a constant track then riders will feel the “jerks”
Lights, cameras, action! This new coaster is gonna have everyone running towards the entrance! There is a new coaster coming to town called the Hollywood Coaster of Fame! Hollywood Coaster of Fame is a coaster based on the bright lights and stardom of Hollywood. Riders will experience a speed from 0-75 miles per hour which will shoot the riders up a 195-foot hill. Before dropping down the hill the riders will feel a bit of suspense on the very top of the hill, which is where the potential energy is the highest. Then riders will feel the weightlessness of dropping down the 195-foot hill into the first loop where gravity pushes down into their seats. The momentum of the loop will take them around a sharp turn making
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? Why do they not fall off of the track when it goes through a loop? The answer to these questions and others about roller coasters lies in the application
How high do you have to make the starting point of the roller coaster in order for the marble to “loop the loop”?
When we first started learning about energy, I instantly loved it because was just so good at dealing with whatever equations and systems I could throw at it. As opposed to kinematics, for example, using energy to solve problems and equations works for almost anything because it can operate pretty well no matter the change in acceleration. All energy needs most of the time is mass, velocity, height, and gravity, and these things are exactly what the roller coasters such as the ones at Six Flags need as well. Roller coasters have no motors. They simply use gravity and height to gain speed to have the ability to traverse loops, twists, and whatever else may be on the track.
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 basically made up of potential and kinetic energy. Once you start moving that's when you're pulled by a motor and that's the only time you have a motor . You're not being pulled by a hitch all the time. Once you're moving you're on your own.
The origin of the roller coaster can be traced back to Russia and their ice slides. These slides were made of ice as they were more prominent during the winter festival, and what a better way than to use the ice that was around them. The ice slide can be traced back as early as the 17th century, to the time of Catherine the Great and they were found mainly in St. Petersburg, Russia. The structures that supported the slides were constructed out of wood and the surface was covered with a thick sheet of ice made of many inches thick. Riders reached the top of the slides via the stairs that were located at the back of the slides. Once they reached the top they descended a 50 degree drop and this exhilarated many and even those members of the
The ride begins with a climb to the top of a 367-foot hill at a constant speed, where the car will reach its highest potential energy. Within seconds the coaster dips down toward the ground and races away, accelerating, from the top of the hill while riders are in freefall. The coaster does not stop when it reaches the ground, though, it continues underground reaching an air pressure that could pop your eardrums. Not a minute later the coaster returns above ground into a loop, creating a great centripetal force toward the center of the current loop. Succeeding the loop the coaster comes to a halt at the bottom of a small hill in a dark building. Instants later the train is shot forward by a hydraulic system using the basics of Pascal’s Principle, causing riders to experience inertia jerk. Following the burst of speed at 95 mph, the roller coaster will go through an intense escape from the police, including sudden brakes where friction has the most effect and sharp turns creating extreme lateral g-force. At the end, there is a small sloped hill causing momentum roll because of the previous momentum from the main part of the ride. The remaining story of the police chase is only known by those who have experienced the stimulating
Today’s roller coaster are built to its extreme capabilities with more speed, bigger and longer to achieves its maximum thrill, now with additional variety of material they are far more durable and strong. The combination of intelligent minds and technological advances has allows us to continually strive higher and bigger than before.

Once accordingly in the building, the passengers will experience inertia from the directional change that happens when going up and down hills. From here on, the coaster will make its way to the Stone Hedges. In the meantime going around the Stone Hedges, there will be centripetal force, and as a result of the centripetal force, the coaster can move up the next hill faster with the assistance of a chain. At any rate going down the hill and witnessing the beauty of Victoria Falls, the coaster will accelerate and move down the ramp into the cave, which is where the gravity pushing the coaster down even more and the weight from the coaster itself will increase the speed. The passengers will experience the Giant Crystals that are throughout the cave while weaving through them. At this point the ride will come to an end, but before that a balanced force will take place by going on the straight rack leading to the end. Friction is bound to slow down the coaster so the passengers don't crash and instantaneous speed will take place when the change in speed slows
The inversion stands at 171 ft, beating the previous record holder by 11 feet. The actual height of the coaster is 200 ft, while the drop length is around 190 feet. This gives a 19 foot difference between the drop length and the loop height. This means the loop is 90% the height of the drop, so 10% was lost in between. The coaster does travel for nearly four thousand more feet after this, but this can’t have any type of correlation to the foam tube coaster. The percentage also is likely realistic by the heaviness of the roller coaster cars, compared to the extremely light weight of a marble. To find if this ratio is common place, I will research another looping coaster. Superman: Krypton Coaster at Six Flags Fiesta Texas contains the largest loop in North America of any non-launched coaster. Launched coasters are practically incomparable to any model that I build due to the fact that they do not contain a traditional drop or hill, so the properties of energy are entirely different. Superman contains a loop measuring 145 ft tall, which is 16 feet shorter than Flash, but still massive
Gravity is a natural force that acts on every thing, and every one on Earth, it is the force that keeps us down to the ground. How does a roller coaster defy a 360-degree loop without falling down toward the ground? Lets take a look at the factors that affect the loops of a roller coaster. Gravity is counteracted by the force of acceleration, which is force that can either be forwards known as positive acceleration, or negative which is known as negative acceleration (Everyday Mysteries, 2013). A roller coaster is not powered by a engine compared to a car.
Some new advances in roller coasters are cables and chains. By adding cables and chains roller coasters can keep the carts from falling off. Roller coasters have come a long way from wood carts and ice.
Roller coasters can be very different, but they usually follow the same basic track to make the ride more thrilling.The ride starts when the chain pulls the cars up the first hill. The first hill is the tallest, so the potential energy is at its most at the
This roller coaster delivers fast twisted drops, exciting laterals and is extremely satisfying. In other words, this roller coaster brings out powerful forces in nearly every twist and turn. It delivers a superior ride experience while retaining the best elements of many roller coasters with additional new elements that make it much more
