The Physics of Roller Coasters
People sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance, you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia, gravitation, and centripetal forces and utilizes different types of energies such as potential and kinetic energy. Physics is what makes roller coasters safe and effective. It is not only the high speed of the trains of a roller coaster that makes the ride so thrilling but the acceleration of the train and the occasional feeling of weightlessness. At various times, roller coasters, or more specifically the trains of these, undergo acceleration, which is defined as the rate of change in velocity. The change may be in speed (magnitude) or direction, or in both. Roller coasters accelerate when they speed up and make the ride faster, slow down, or change direction. It decelerates as, for example, it ascends as if going up a hill. In this case, acceleration is dependent on its mass and the other forces acting on it. It is the acceleration of roller coasters what makes the ride more thrilling and exciting. When riding in a roller coaster a person may at some point feel weightlessness because they do not feel the chair they are sitting in as the roller coaster and yourself move vertically at 9.8 m/s^2. Therefore, you encounter with Galileo and Newton’s principle of free fall, an object moving under the influence of gravity only. Newton’s laws of motion state that the sum of the forces acting on free-falling objects, gravitation and its inertia, equals to zero. Because these forces add up to zero as gravity cancels out with the object’s inertia, then the rider while riding in an arched

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…

A roller coaster train going down hill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.…

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…

600 years ago, roller coaster pioneers never would have imagined the advancements that have been made to create the roller coasters of today. The tallest and fastest roller coaster in the world is the Kingda Ka, a coaster in New Jersey that launches its passengers from zero to 128 miles per hour in 3.5 seconds (most sports cars take over four seconds to get to just 60 miles per hour). It then heaves its riders skyward at a 90-degree angle (straight up) until it reaches a height of 456 feet, over one and a half football fields, above the ground, before dropping another 418 feet (Coaster Grotto "Kingda Ka"). With that said, roller coasters are about more than just speed and height, they are…

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 so fast. It is a roller coaster that is never seen before. When you see some roller coaster have some loops and small turns, well this is the complete opposite. Consequently, You will experience so much during the ride and what is even better is if you chose to ride in a cart that will go twice around for a little bit more so you do not have to wait in line again to ride it another time. The carts are aerodynamic so that he has less air resistance they will have a higher speed. I personally like roller coasters that are fast so with this being more aerodynamic which will allow it not to slow down while allowing it to not decrease in speed. When you are going down the hill you will always feel weightlessness which is when you lift out of your seat like you're flying. It has an acceleration…

A problem with this type of roller coaster is that the cumbersome, heavy track unables the design to have complex twists and turns. The track of wooden coasters mostly consists of the motion going up and down, also know as hills. An example of a wooden roller coaster would be the Ghost Rider in Knotts Berry Farm and Goliath in Six Flags. Another type of coaster is the steel roller coasters. Steel roller coasters were first introduced in the 1950s.…

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…

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).…
