Roller Coaster Physics
For many people there is only one reason to go to amusement parks, the roller coaster. The past of roller coaster in a never ending search for crazier and more death defying thrills. A lot of people wonder how do they really work? If a person were to step back and look there is no engine on the cars. So, how do they work and what makes them really move? The whole idea behind the roller coaster is the transfer of energy. The conversion of potential energy to kinetic energy is what drives the roller coaster around the track. All the kinetic energy you need is produced upon descending the first hill. The roller coasters have different types of wheels to make the ride the most enjoyable to the rider. The friction wheels maintain lateral motion. Running wheels guide the roller coater on the track. The last set of wheels keeps the ride on the track even if it’s inverted. The tracks are also a big part of the physics concepts behind roller coasters. When coasters are made there is a large amount of thought put into the designs. The coaster tracks are what channel this force they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it slows down. The whole idea behind roller coasters is both a thrilling and genius concept based on both physical science and conceptual physics.

As the height of the roller coaster increases, the speed of the marble decreases; and vice versa. When the height of the roller coaster is at it’s peak, the highest point, and the motion of the marble is going uphill; the speed has less kinetic energy than it has potential. The potential energy is being stored up, as the marble’s velocity is at an upward motion. Once the ball reaches the highest point and starts moving in a downwards motion, it releases the stored energy and gains kinetic energy. While the marble is in motion, both the potential and kinetic energy have to be balanced. For example : the top of the second hill contains a 50-50 relationship between kinetic and potential energy. As the ball goes downwards, the kinetic energy becomes more than the potential energy, and vise versa when the ball goes uphill. As an example, positions 1 and 5 are the positions that the object gains potential energy; the speed at position 1 is 38.31 cm/sec, and the following two speeds show the effects of kinetic energy. Position 2’s speed is 150.79 cm/sec and position 3’s speed is 180.95 cm/sec. On position 4, the object gains potential energy and loses kinetic energy because of the uphill motion, speed at position 4 is 155.74 cm/sec; and on position 5, the speed is 106.74 cm/sec. The change in these speeds show…

For our car we decided to make it a rubber band car since that would give it the most mechanical and potential energy. The rubber bands were to act as our potential energy since it stored all the energy as we pulled it back to wind it up. The whole car then would be running on mechanical energy. As the rubber bands unwind, it turns the rear axle of the car which then drives the rear tires to move the car. Miranda made sure to get the car to only go forward by figuring out the right amount over rubber bands and how tight to make them. Another way to not make sure the car went a different direction was to make sure the bands released and didn’t get twisted back up. If they did that would result in a car that went backwards. The tighter we got them the father the car would go. It turned out to be about 4 bands that were tied together. The car was able to go because of the force that was being built up with the bands as they tightened. The back wheels were also put on tight so the car went straight and the axle was secured with glue to the rotating piece of wood. The only force acting on the car were the bands and with the cement ground there was no friction, so the car had a smooth ride. The speed did slow down however after the initial take off but we wanted it to go slower as it approached the wall for the safety of the egg. Overall our project went really well.…

When you are riding a roller coaster, have you ever wondered what keeps you in your seat when you go through a loop, corkscrew or helix? Or are you too excited to even notice? There are literally only two types of roller coasters. One type is a steel roller coaster. Another type is a wooden roller coaster. Even though they are made of different materials their needs to operate are the same. Every roller coaster needs a launch, physics and a good braking system. So to fully understand how roller coasters work it is essential that you know how a roller coaster launches, uses physics, and how it brakes.…

First, to understand how a rollercoaster works, one must understand what exactly defines a rollercoaster. Generally, they have several drops and valleys, loops and turns, which are all traversed through the manipulation of its kinetic andpotential energy. For example, in most situations a roller coaster car will initially be pulled a large hill. As the suspense for the riders grows, so does the potential energy. Once at the top, the ride’s built up potential energy is turned into kinetic energy by the…

Many Americans have fears of all kinds. One fear is roller coasters. Individuals who have this type of fear may also have the fear of heights and how high the drop is on a loop or how fast the coaster goes. They have the feeling as if they are going to fall if up too high or how queasy their stomach may feel with the thought of approaching the big loop. This type of behavior can come from something as little as tripping off a curb or falling off a bike which triggers them to be afraid or fearful of anything that is high up. When it comes to individuals with the fear of roller coaster there is something in the mind telling them that they are too high up which…

The roller coaster is made out of steel piping so that when you are traveling there is going to be less friction and as we know friction slows you since heat is being created. This roller coaster is the bomb and I personally think everyone should try it. Nevertheless, I can guarantee this will be a spectacular experience I can assure you this will one of the best roller coaster you have ever been on I have spent so much time researching what people like most in roller coaster ad that is why this is the best because of the thought I have put in it. Ordinarily walking up to the line you will always have a clear view of the roller coaster moving to see how close you are to having your turn. As you are going down the highest point of the coaster that is when you will experience the most kinetic energy. In the beginning, as you are climbing the to get to the top when you are moving that is instantaneous speed since while you're going up it has motors that allow it to climb high and fixed speed of motion the speed never changes when it is…

Simply speaking, a roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track.[1] 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. The forces experienced by the rider are constantly changing, leading to feelings of joy in some riders and nausea in others. The basic principles of roller coaster mechanics have been known since 1865,[citation needed] and since then roller coasters have become a popular diversion.…

If you choose the dark side, you will be riding in a TIE Fighter. Regardless of which side you choose, your ride will begin with a steep incline up a hill at a constant speed. Once you reach the top of the 148 foot hill, where lots of potential energy is stored, you begin your descent down the hill at 90 miles per hour, the fastest velocity yet. During this free fall, gravity is the only force acting on you, and you are weightless. You then use the momentum and acceleration from the previous hill to perform two loops. During these loops, you have centripetal force to keep you in your seat. Once out of the loops, the two roller coasters meet in the middle for a battle on Hoth. During this battle, the coasters are twisting around each other. At the conclusion of the battle, both coasters will travel up yet another hill. Upon reaching the top of the hill, the light side coaster will wind around R2D2, and the dark side coaster winds around the Death Star. Both coasters then enter a vicious corkscrew prior to entering light speed tunnel and racing home. Once a winner is determined, the coaster will slow down due to the friction of the breaks. Riders may feel a slight inertia jerk when this is…

Roller coasters, one of the best amusement rides that ever existed. This amazing ride traces its origins back to Russia where it all began (Source E). Russia is where wood-framed ice slides sent sledders down 70- foot high slopes in the 16th century, in St.Petersburg, Russia (Source E). Since, Russia was a snowy place, the sleds were a perfect pastime. The roller coaster was built out of lumber with a sheet of ice several inches thick covering the surface to make sure it was as safe and sturdy as it could be (Source F). The riders climbed the stairs attached at the back of the slide, and they sped down a 50 degree drop (Source F). The slide were mostly ridden by the upper class of Russia (Source F). During the winter festivals in Russia, the…

[4] After the roller coaster is drops from the first hill it does two things with its energy. First, it begins to transform that energy from one form to another--from gravitational potential energy to kinetic energy and from kinetic energy to gravitational potential energy, back and forth. Second, it begins to transfer some of its energy to its environment, mostly in the form of heat and sound. Each time the roller coaster goes downhill, its gravitational potential energy decreases and its kinetic…

Looking at how they are designed and made are fascinating. An example of one of these would be the starting mechanism called the Catapult-Launch Lift. They are devices that shoot the train out at high speeds instantaneously. One of the most popular versions used today are Electromagnets. Electromagnets are used inside of linier-induction motors in order to build two magnetic fields, one around the track and one around the train car. (How Stuff Works) The magnetic field that the motor creates on the track pulls the magnetic field that is attached to the car which pulls the cars as fast as the motor pulls the magnetic field. There are many advantages to these systems, for example, speed, efficiency, precision, and control. All roller coasters that run need a safety process installed just in case something went wrong. Also to make sure that the cars can safely come to a stop at the end of the ride. These are the brakes. Most use a hydraulic system that closes clamps onto the train car when it needs to slow down. The clamps are usually found on the tracks themselves and gradually put friction on the cars until they gradually slow down. I feel that roller coasters are some of the greatest ways to entertain people. They are very simple when it comes from a physics standpoint. Gravity is doing most of the work and is just assisted by many precautions and safety measures to…

Firstly the physics behind the rides. The acceleration is what makes rollercoasters so fun and enjoyable and I’ll now explain why they accelerate so quickly. The purpose of the coaster's initial ascent is to build up its potential energy. As the coaster gets higher in the air, gravity can pull it down a greater distance meaning the potential energy increases. You experience this phenomenon all the time; think about riding your bike or pulling your sled to the top of a big hill. The potential energy you build going up the hill can be released as kinetic energy (the movement energy that takes you down the hill).…

At thirteen years old, I was the kid that no one wanted to drag to an amusement park with because I strictly stuck to the merry go round and swings. My parents were always eagerly trying to persuade me to at least try a roller coaster but I refused. Deep inside I wanted to be fearless and be able to jump on the attraction like there was no problem, but I was too nervous. All of my friends, including my family were adrenaline junkies, always wanting to get on the roughest and worst rides of them all. This naturally caused me to become even more frustrated when attending Silver Dollar City in Branson, Missouri, which was very often. It wasn’t till one day when visiting the park that I decided I was not just going to take a risk, but I was determined to overcome my first roller coaster.…
