A motor or chain pulls the roller coaster cart up a large hill in order to gain potential energy. This energy is dependent upon the mass of the cart and the height of the cart. Once the cart goes down the hill and begins to descend onto the first loop most of the potential energy is lost and is converted into kinetic energy. This energy is dependent on the mass of the cart and the speed of the cart. Due to the fact that roller coasters are constantly going up and down the energy is continuously changing between potential and kinetic energy. When the roller coaster gains height than the speed decreases which represents the change from kinetic to potential energy. Whereas, when height decreases the speed increases in the transformation of potential …show more content…

The work in this equation relates to outside forces such as air resistance. When the roller coaster ride begins the forces acting on it are the force of gravity, normal force, and dissipative forces (which is the work done externally on the cart). The force of gravity and the normal force both have no effect on the work done on the carts. This is due to the fact that the force of gravity is internal and the normal force is perpendicular to the motion. However, the dissipative forces do. Through this, a small amount of the initial energy is taken through the dissipative forces, which is why the W is included in the equation. However, this amount of energy is very small so it can sometimes be neglected. When this occurs than the combination of potential and kinetic energy (mechanical energy) is conserved throughout the ride, meaning no energy is …show more content…

The roller coaster has 10 cars attached to it and each car is single-car. It has a mass of 950 kg. Each passenger will weigh approximately 75 kg. On this ride the height of the first hill will be 100 meters tall. The bottom of this hill will have a slight curve so it similar to a free fall. The next hill would be 90 m tall in order to give the cars the maximum amount of possible energy. The loop would be an elliptical loop that is 55 m tall. In order to find out if potential energy is converted into kinetic energy the equation stated above about roller coasters will be

Roller coasters are a great thrill, but Cedar Point has Kings Island beat in many areas. Cedar Point is a better amusement park than Kings Island, because it has the biggest rides, has more world records, and has a greater variety of rides for everyone to enjoy. Cedar Point is home to the tallest roller coaster in the world, the Top-Thrill Dragster. This monster is 420 feet tall and reaches speeds of 120 mph, that’s 190 feet taller than Kings Island’s ride and 40 mph faster. In just over three seconds

Title: Introduction: A-mountain lies in Southern Arizona, a region known as a desert. There are factors that contribute to the growth of certain plant life in certain areas. The north and south side of the mountain is expected to have contrasting difference due to the amount of sunlight each side receives. Exposure to sunlight affects the plants growth and overall life.

Each of them have a unique design, that would cause it to have special features for each individual ride. Each had a basic metal structure, but an individual outline. My favorite consisted of steep inclines and fast drops, that would leave the passenger feeling heavier than they would normally. I also loved the rapid rate of speed during a ride. It was most interesting that we got to learn the engineering process of a roller coaster.

No clicks, only muffled screams. This rollercoaster did not plummet on the path, no, it tipped off the tracks. It was suspended in mid-air only for seconds, before gravity grasped its meaty hands around the car and forced it downwards. The janitor kept his whistling, busy in his thoughts; not to blame. It was silent until too late.

Physics, period 3 Malak Mokhles Data collection: Jan To measure the period of a swinging stopper for three selected radii in order to calculate the centripetal force Data Table Calculations Calculate the centripetal force acting on the stopper. (Fc=mac) 50 cm radius: (0.025kg)(50m/s2)=1.3N 35 cm radius: (0.025kg)(43m/s2)=1.1N 25 cm radius: (0.025kg)(39m/s2)=1.3N State the weight of the washers 50 cm radius: 15 washers=0.75N 35 cm radius: 15 washers=0.75N 25 cm radius: 10 washers=0.50N Calculate the percent error for each radius (% error =|theoretical - experimental /( theoretical ) | × 100%) 50 cm radius: |0.75 – 1.3 /(0.75) | × 100% = 73% 35 cm radius: |0.75 – 1.1 /(0.75) | × 100% = 47% 25 cm radius: |0.50 – 1.0 /(0.50) | × 100% = 100% Analysis/Discussion

The operator then repeated the same facts as he did the last group. “You will first take a 30 second ride up to the top of the 230 tower. Then, suspended at the top, you will be dropped at speeds of 70 miles per hour. Enjoy you ride on the Superman: Tower of Power!” The ride then roared to life as we slowly began the climb to the top of the

The purpose of this project was to understand how the elements of physics allow a roller coaster to function. By the end of this, we will be able to distinguish the energy behind a roller coaster and how the laws of physics allow it to stay in motion and guarantee the passengers safety, demonstrated

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

A lever is a board or bar resting on an object called a fulcrum, and a wheel and axle is made out of a rod going through a wheel. Even though there are many different kinds of energy, the two main ones are kinetic energy and potential energy. Kinetic energy is the energy that an object has while it is motion. The faster an bject moves the more kinetic energy it has. The kinetic energy increases as its mass increases.

Trolley problem, initiated by Philippa Foot, is a situation in which there is a runaway trolley and the only way to save five people on the tracks is to sacrifice one person (Kvalnes, 2015). There are many versions of the trolley problem with regard to how the one should be sacrificed, make trade-offs in order for five persons to be saved. In this paper, there are two trolley case used to compare with the autonomous car case. The first case, called the switch case, come from Philippa Foot (1967), in which there is a third person who are standing next to a signal switch.
