The Physics of Amusement Park Rides
The amusement parks we known today have an interesting history, that come from European fairs and pleasure gardens. The Worlds Fair was very influential in the creation of amusement parks. The first Worlds Fair in 1851 held in London began the thought process in creating a fun environment for large exhibitions. With that the first amusement park was born 44 years after the first Worlds Fair. This amusement park was the first enclosed park entertainment area in amusement rides, the infamous Coney Island. From then amusement park rides began to be born, with the help of ideas founded upon 169 years earlier by Sir Isaac Newton. Amusement Park rides are divided into three categories; flat rides gravity rides,
However gravity rides contain other forces at play such as Newton’s second law: bumper cars, and circular motion: merry-go-round. Newton’s second law states “The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.” (Forces, 2015). Looking at bumper cars we can see how forces play a role, along with momentum. Where the collisions are elastic, and the force of the collision is felt upon the rider wanting to keep moving in the same direction. These elastic collisions are when the total momentum and kinetic energy are conserved, and there is no loss of momentum or kinetic
The vast majority of rollercoaster start with a steep motorized climb in elevation or gain in potential energy. Once at the top, the roller coaster has enough potential energy to make it back to the loading station. The roller coaster uses its stored potential energy and converts it into kinetic energy to carry the car throughout the track. Further examining the wheels on a rollercoaster, the wheels operate under circular motion, and rolling without slipping. Looking at figure (3) we can further examine rolling motion. Translational motion is the movement of an object from one point in space to another. Rotational motion is the motion of a rigid body where every point on the body moves in a circular path. Combining these two motions gives us rolling without slipping. Where the velocity at the top of the circle is twice the velocity of the center. Since the velocities at the bottom of translational and rotational are antiparallel and cancel each other. The velocity at the bottom where contact is made between the circle and ground is
Every year an estimated 290 million people all over the world flock to amusement and theme parks to experience the thrills and excitement of the modern day roller coaster. (Boldurian 16). Now thousands of people a day can safely experience the G-forces that an astronaut or fighter pilot would experience in flight. "The Revolution" a roller coaster at Six Flags Magic Mountain in Valencia California gives riders an amazing 4.9 Gs; that is 1.5 more than an astronaut at launch. (Boldurian 16). These G-forces create thrills and fear and excitement in all who ride them. But the truth is that there is no reason to fear. Roller Coasters are exceptionally safe. The mortality rate for roller coasters is one in 90 million, and most of the fatality occurred due to failure to follow safety guidelines. (Boldurian 17). But roller coasters have not always been this safe. One of the first coaster attractions was actually just a mine rail designed to bring coal to the base of the mountain (Lemelson-MIT Program). The attraction was a thirty minute ride, with speeds of more than one-hundred miles per hour. As time went on entrepreneurs in the late 1800's began creating “quick buck cheap thrill attractions.” These early coasters lacked safety for the sake of thrills. This changed when John A. Miller engineer and roller coaster designer began making coasters. John Miller held over 100 patents many of which were for roller coaster safety and functionality that are still used today (Lemelson-MIT Program). John Miller's inventions and improvements to the roller coaster make him the father of the modern roller coaster that we know today.
Gravity is the force that attracts a roller coaster to the Earth and determines how far along the track it was pulled. When a roller coaster crests a hill, the gravity takes over and pulls it along the track at a “constant rate of 9.8 meters per second squared”(1) according to the website Wonderopolis’ article titled “How Do Roller Coasters Work?”. This numerical value, (or concept), is called the acceleration of gravity. It means that no matter the shape, size or mass of an object on Earth, gravity will pull it down at a rate of 9.8 meters every second, assuming there are no other interfering factors to mess with the decimal. In the article “How does Gravity work?” Tom Harris describes gravity and height’s relationship by stating, “As the coaster gets higher in the air, gravity can pull it down a greater distance” (1). This means that if a roller coaster were on top of a hill one thousand feet high, it would be pulled a lot further along the track by gravity than a coaster on a hill with a crest one hundred feet. Why? Because the coaster at one thousand feet has a stronger pull towards the Earth and can go farther because of it. The aspects of gravity, the acceleration of gravity and its relationship with height, are all important aspects of the force gravity. In conclusion, gravity is a vital, while fascinating, type of phenomena to observe in roller
The result and the final decision court will depend on the laws of that state. While a majority of states has chosen to institute a rule where they hold amusement ride operators and owners to the standard of ordinary care in operating their rides, a growing minority of states, including Illinois, hold those same operators to the duty of utmost care. The importance of a consistent standard for roller coasters is imperative to raising the expectation of safety, thereby preventing many of the accidents that occur every
Carowinds is compiled of many gravity-defying rides. Top Gun: The Jet Coaster is the Carolinas’ only inverted steel roller coaster. While on the ride, you are hurled through six swirling inversions while in the air. The Vortex is a stand-up roller coaster that takes you on a 50 m.p.h. series of loops and drops. Drop Zone Stunt Tower is a ride where you can experience the rush of gravity as you descend sixteen stories in seconds
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.
Roller coasters come in all sizes and configurations. Roller coasters are designed to be intense machines that get the riders’ adrenaline pumping. Ever since my first roller coaster ride, I knew I was hooked. I cannot get enough of the thrilling sensation caused by these works of engineering. When people board these rides, they put their faith in the engineers who designed the rides and the people who maintain and operate the rides. In this paper, I will bring to your attention a specific instance when the operation of one of these coasters came into question and led to a very tragic incident. From this, I will look into the events leading up to the incident and evaluate the decisions made by the people involved.

“A roller coaster is essentially a gravity-powered train (2).” Gravity is the weakest of the four physical forces, but when it comes to roller coasters, it is the dominant one. It is the driving force and what accelerates the train through all the turns and twists. Gravity is what applies a constant downward force on the cars. The deceleration or acceleration mostly depends on the inclination of the angle relative to the ground. The steeper the slope is, the greater the acceleration, and vice versa.

In 1955, the company went a notch higher by opening its first theme park in Anaheim, California. This saw the beginning of a journey of success and growth.
Amusement parks are by far one of the most thrilling places on earth. As you wait in a long line to get in park, you can hear numerous kids, adults, and tourist shouting off the top of their lungs due to a tremendous jaw-dropping drop on their beloved roller coasters.
Since the velocity of an object rolling on wheel(s) is equal the radius of the wheel times its angular velocity we can substitute V2 in for r2w2. This substitution leaves us with:
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Eren watched the retreating backs of his two best friends as they walked on ahead chatting animatedly with each other as if they haven’t wronged him in any way. How could they betray him like this? Mikasa must’ve noticed her brother’s grumbling behind her because she stopped and pressed her finger into his forehead without him realizing. The jolt surprised him and anger overtook surprise in a matter of seconds.
I have always been fascinated by carnival rides. It amazes me that average, ordinary people eagerly trade in the serenity of the ground for the chance to be tossed through the air like vegetables in a food processor. It amazes me that at some time in history someone thought that people would enjoy this, and that person invented what must have been the first of these terrifying machines. For me, it is precisely the thrill and excitement of having survived the ride that keeps me coming back for more.
