Explanation of the Physics Involved
For a thrilling experience in a rollercoaster ride, there is a wealth of physics involved. A part of the physics of a rollercoaster includes the physics of work and energy. The Redback is a pendulum type ride at Aussie World that includes many types of physics concepts. These concepts include the conversion of gravitational potential energy to kinetic energy, G-force, the conservation of energy and simple harmonic motion. The calculations of the ride of the Redback can be seen in Appendix B.
As roller coasters travel down and up the track throughout the ride, the gravitational potential energy (GPE) the cars hold is transferred to kinetic energy (KE), and back again. On Earth, there is always the force of gravity acting on people and things. This is called GPE. The amount of

Therefore, the equation is GPE=mgh. All moving objects have kinetic energy. The kinetic energy an object has depends on its mass, if the mass doubles then the KE doubles, and speed, if the speed doubles then the KE quadruples. In order to find KE, the formula KE=½ mv^2 is used. As the car travels to the top, or highest point in the ride, the car gains GPE. However, once over the top, the car then gains speed as GPE is transferred to KE. Note that not all the energy is transferred to or from GPE, as some is transferred to the surroundings as heat and sound. However, for this investigation, it is assumed that all energy is transferred. No energy is lost or gained. Which is the Law of Conservation of Energy. The Law of Conservation of Energy, a concept
Neither Timber Terror nor Tremors has an engine or anything pushing the cars along the track. The only time the cars are aided by a machine is when the car is being carried to the top of the first hill and the compression brakes at the end, but from then on, the cars are in the hands of potential energy and kinetic energy (“Roller Coaster”). Mechanical energy is used to lift the train cars to the top of the hill. Once it reaches the top of the hill, the car has a very large amount of potential energy. After the car reaches the top and begins its descent, it loses potential energy with the loss of height and gains kinetic energy. Each time the coaster goes up a hill, it loses kinetic energy and gains potential energy (“Energy Transformation”). Although potential and kinetic energy play the largest roles in the physics behind a
Acceleration is another form of energy. When the rollercoaster takes off, the acceleration is the Form of energy that makes the ride goes its certain speed.
As the car go down it looses its potential energy because it is not at the same height anymore. As it loses the potential energy it gains kinetic energy. Kinetic energy came along because of its high speed. The mathematical equation for this is initial kinetic energy plus initial potential energy plus external work equals final kinetic energy plus final potential energy. To find work the equation is force times distance. To find power the equation is work divided by time.
While at the asylum, your body will feel heavier from high amounts of G-force. The reason why your body will feel heavier is because of the twisting and turning off the tracks. As you exit that room, you will experience complete darkness, until you finally reach Mary Anne’s obscene memory with Dr. Bumby. The ride is going fast, so it’s increasing its acceleration at this point. Once you get to the highest point of the ride, you experience the highest amount of potential energy. The coaster tracks then curve, creating centripetal force. As the ride begins to go up, you experience maximum kinetic energy just as the riders pass through the bottom of the loop. When the memory between Dr. Bumby and Mary Anne finalizes, there is only one room left before the entire ride ends. As the rider is going down the straight track, there is less energy at the end of the ride than at the start due to friction and air resistance. The ride ends off with the rider going through the cat’s
The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.
Potential and Kinetic energy plays a big role in the roller coaster´s energy to go up and down hills during the ride. Let me start it off by explaining what potential and kinetic energy is, Potential energy is stored energy that is kept for when it needs to be used. Kinetic energy is energy in motion, for example when a roller coaster is going up the initial hill the train is using potential energy but as soon as the chains let go at the top of the hill the coaster is using kinetic energy because the train is in motion. These energies play a part in this specific place because when a roller coaster is using potential energy it is saving and storing energy and not using anything because the train isn't in motion. On the other hand kinetic energy
Then as the coaster begins its decent down the first hill, the energy is converted back into kinetic energy as the train is pulled toward the Earth by gravity. Gravity is the traditional source of power for roller coasters that accelerates the train as it goes on its hilly, twisty journey.3 Gravity is a unit of acceleration, that is always present, that causes free-falling objects on Earth to change their speed at a rate of approximately 10 m/s (32ft/s) every second.1 So, as the train goes down the hills of the track it has a positive acceleration giving it the necessary potential energy to “climb” the next hill, make a turn, or travel through a loop.
Potential energy is energy that is stored in an object due to its position. The roller coaster has high amount of potential energy at the beginning of the ride. Throughout the ride, potential and kinetic energy are constantly swapping back and forth until the ride ends. Each time the roller coaster goes up a hill it gains more potential energy. The kinetic energy of an object is the energy that it possesses due to its motion. There's a maximum kinetic energy just as the roller coaster passes through the bottom of the loops. At the end of the roller coaster there is more kinetic
a roller coaster is moved only by the forces of inertia and gravity. The only exertion of energy
When we eat food, like a juicy hamburger, it gives us energy that we save to use later when we do something, like go for a walk. Kinetic energy is the energy of movement. When you walk, your body is using the saved energy from your food and turning it into kinetic energy for movement. Just like when the kinds of energy change when you walk, roller coasters also change potential energy into kinetic energy. They depend on things called momentum and gravity too!
One type of physics the ride uses is ‘acceleration’ objects that are changing their speed or their direction accelerating. The rate at which the speed or direction changes is referred to as acceleration. Some amusement park rides (such as roller coasters) are organized by rapid changes in speed and or direction. These rides have large accelerations. Rides such as the carousel result in small accelerations; the speed and direction of the riders change over time.
When you start moving that's when the motor lets go then you have kinetic energy when it falls it builds up enough energy to propel the rest of the ride. Even though you don't notice or think about it gravity is the reason you stay on the track.
Second Law: The acceleration depends on the mass of the rollercoaster and the force of gravity that is pulling the rollercoaster.
Our task was to build a rollercoaster out of stryrofoam tubes and have a marble make it through the Styrofoam tubes form point A to point B. The one thing you have to change when you start off is… your idea. And I say that because, once you get started you realize that when you try to coordinate the must haves. You see that your marble either looses kinetic energy or has to much. Therefore, causing your marble to not have enough kinetic energy to not make it to the end of the coaster. Whereas, the easiest part was building the starting point of the rollercoster to get the marble started. For example, each gain in height corresponds to the loss of speed as kinetic energy (due to speed) is transformed into potential energy (due to height). Each
The cars on a typical roller coaster are not self-powered. A standard full circuit coaster is pulled up with a chain or cable along the lift hill to the first peak of the coaster track. The potential energy accumulated by the rise in height is transferred to kinetic energy as the cars race down the first downward slope. Kinetic energy is then converted back into potential energy as the train moves up again to the second peak. This hill is necessarily lower, as some mechanical energy is lost to friction. Not all rides feature a lift hill, however. The train may be set into motion by
