Transportation Experiment

2050 Words9 Pages

Abstract: Form the beginning of time, how to travel farther and faster was one of the main concerns for humanity. People invented lots of different types of transportations and improved them as time passed enabling themselves to use these transportations travel in more difficult terrain and harsher environments safely. One of the very most important aspects of any transportation is its external design, which affects the magnitude of the friction that is acting upon it. I have always been attracted to the large variety of cars, planes, ships, submarines and other transportations that travel around Earth or even in outer space transporting different kinds of cargo from one destination to another. The aim of this Extended Essay is to examine …show more content…

The equation Fdrag = m(g – a) would be used in the experiment to help calculate the magnitude of the air friction on the object at the instant. The experiment is conducted in the morning, from 7:00 – 9:00, and the location is indoors, to minimize the effect of wind on the experiment. Hypothesis: The hypothesis for this experiment would be that the cross-sectional area of an object and the air friction that is acting on it at the same instant are directly proportional to each other. Variables: Dependent variable: the magnitude of air friction at the certain instant. Independent variable: the cross-sectional area of the object. Controlled variable: the mass of the object, initial velocity of the object and wind speed. Uncontrolled variable: air density. Materials: A mass with mass of

    In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.

    The US went through revolutionary advancements in transportation from 1800 to 1840. The transportation improvements had substantial effects on the economy and also individual development. People could now buy goods that were made in places faraway because access was easier to towns and cities and people’s experiences grew as they were able to be more mobile (309). The roads were inadequate in 1800, so the federal government funded the National Road in 1808 to establish its dedication to improve the roads in the nation and so then by 1839 the East and West would be tied together (309). Commerce was still inadequate even with the National Road funded which improved transportation.

    My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

    The building of roads, canals and railroads played a large role in the United States during the 1800s. They served the purpose of connecting towns and settlements so that goods could be transported quickly and more efficiently. These goods could be transported fast, cheap and in safe way through the Erie Canal that was built to connect the Great Lakes to New York. Railroads were important during Civil War as well, because it helped in the transportation of goods, supplies and weapons when necessary. These new forms of transportation shaped the United States into the place that it is today.

    The hypothesis for this project was “If a soccer ball has less regulation air pressure, then the distance the ball travels when kicked will be less.” It was therefore rejected. The soccer ball with less air traveled farther than the soccer ball with more air. The average distance of the soccer ball with less air traveled 29 yards, and the soccer ball wind or that I was tired.with more air traveled at an average distance of 19 yards. could’ve been caused by the It Everything went according to plan except that the hypothesis was rejected.

Both variable mentioned are going to measured (height and time taken), when conducting the experiment. In order to have a fair experiment, certain factors will be kept the same throughout the experiment: the same paper cup will be used, the dimensions of the paper cup will be constant (where external factors do not affect the shape), the method in which the paper cup will be dropped.

    Data Analysis The problem that this experiment is trying to solve “is the effects of air drag and how to reduce issues”. The solution of the problem was “that reducing build in the front of the car and not using a blocky design will affect the travel of the cars”. The independent variable was the different shapes or models of the cars and the dependent variable was the change of time speeds. The controlled variables were that the same timer was used, each car received sanding, the same track was used for each trial, and the finish line was located at the same place every trial. The control group consisted of one car.
