How Does Air Resistance Affect Air Travel? A Literature Review

Air trajectory is the physics of how an object moves through a “fluid” which can be a liquid or a gas. In the event of Air Trajectory, students launch projectiles a certain distance using gravitational energy in the form of a dropping weight. The involved science is more about the most efficient method of launch rather than how the projectile moves through the air.

Well you may be thinking-- what exactly is flight? Thomas Campbell Foster says, in his book How to Read Literature like a Professor: A Guide to Reading between the Lines, that in general flying is freedom (Foster 134). It can be freedom and/or escape from general burdens, life on earth, and specific situations, or it can symbolize

Q1. How and why has the express mail industry structure evolved in recent years? How have the changes affected small competitors?

Gravity: Gravity is a force of nature that keeps things on Earth instead of floating out of the atmosphere.

The book Flight by Sherman Alexie is about a 15 year-old boy named Zits. His Irish mother dies of breast cancer when he is young and his Native American alcoholic father runs away. He has lived in 20 different foster homes and has gone to 22 different schools. Zits had a very rough childhood which has led him to be a troublemaker. Later in the story he shoots up a bank and then gets shot. As a result of his death, he goes on a “flight” and lives through parts of people’s lives who’ve experienced violence, revenge and betrayal. A scene in Flight where he experiences betrayal is in the body of Jimmy. Jimmy betrays his wife then later finds out that his best friend betrayed him and so many other people. In this scene Alexie suggests that we

The air also affects the flight of a soccer ball. In the air there are little particles known as air molecules. They move around at a certain speed and the amount of air pressure comes when the air molecules are forced against a certain object (NASA, 2004).

“Flying,” by Alice Miller is a complex story about a woman named Allie, who reminisces about a time spent when her cousin Mack taught her to fly when she was just a young girl. On different occasions when Mack visited, he would show her how to do new things. As Allie grew up she found herself thinking of the secret that Mack shared with her and how he told her not to tell anyone or she may get hurt. Allie longed for the feeling of flying, if she could just reach out and talk to Mack but too much time had passed. She dreams of flying in her sleep, not for long periods of time, but just enough to embrace that feeling she had years ago. She wonders if many people have experienced flying the way that she has and if she could fly by herself without Mack. One day, Allie tries to fly on her own and succeeds, soaring higher than she did with Mack. Before Allie knew it, she was flying through the clouds and around town. Now that Allie has experienced the feeling of flying again, more than ever she wanted to share with her kids. One night after the children were asleep she wanted to share her secret with her boys but instead chose her daughter. Miller suggests that when a person is afraid of doing something on their own, sometimes it just takes a little bit of courage to step out and let go of the things that could be holding a person back.

When a person is faced with an awful situation, it is all too easy to only see the negative. Flight by Sherman Alexie, focuses on this through the point of a young teen named Zits. Zits grew up in an abusive and unhealthy environment. (exsmples) When Zits turned fifteen, he met someone that calls themselves Justice who mislead Zits ino shooting up a bank. This leads to his death and a series of body shifts. These shifts make Zits reflect on his own identity and the actions he’s committed his life. By experiencing different stories/lives, Zits is able to learn that, even though there are bad things in the world, there are also many positives to go with the negatives.

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

Lift is one of the most contested components of airplane flight. There are different theories in how an airplane reacts to air being rushed over its wings. In all actuality the entire airplane promotes lift. Often it is forgotten how the top portion of the airplane and wing plays just as an important role in creating lift as the bottom of the airplane and wing. As stated in How Airplanes Fly “Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air” (Eberhardt). Lift must overcome or be equal to the weight of the airplane (Eichenberger). Lift is produced as the air flows over the body and wings of the airplane as it is moving forward. The wings help to develop most of the lift due to their design. They come in different shapes and sizes, from short wings to very long wings, even a propeller of a helicopter is considered a wing. No matter what size or shape, wings are designed to create lift. According to Newton’s third law, for every action there is an equal and opposite reaction. This means the lift of a wing is equal to the change in momentum of the air it is diverting downward (Eberhardt). Pilots have controls to increase the size of the wing while the airplane is flying, thus increasing lift and helping to keep the airplane flying at slower speeds.

     Drag force is the cost of increasing downforce. Drag force is the force acting on an object in motion in the opposite direction the object is moving through a fluid (Yager). To most people drag force is simply known as air resistance. The objective of aerodynamic efficiency is to maximize downforce while minimizing drag force.

Since the beginning of recorded history, humans have always had a fascination with flight. Now that we live in a world where boarding an airplane and flying across the country – or even the world - is simply a part of everyday life, the wonder of flight has diminished for many. Despite this, physics students from all around continue to delight in the many physical forces that play a part in keeping these huge objects (like jumbo jets) from falling out of the sky!

This essay is about sustainable aviation which is going to clarify the meaning of sustainability and arguing that in some cases the idea of sustainability is unachievable and in some cases is achievable. Sustainability is about environmentally friendly, corporate responsibility. Aviation is an increasingly important form of transport, providing very important mode of connections to both passenger and cargos.(Tony2005)aviation is part of sustainable transport but these are all linked together, with most of the companies trying to change them, sustainability’’ has arisen from ecology and the study of ecosystem’’ . Flying got may benefits and also supports the economy and jobs, taking people on holiday to see different people and different cultures . however it also has got lots of problems for those people living around airports and it is a beg and also growing contribution to climate change . it also explains how sustainable aviation has an effect on the environment, the economy an social factors.

In 1943, Theodor Von Karman, in response to a request by US Air Force headquarters, claimed that the realization of a supersonic aircraft would have been doable using the right technology and tools. The fear of breaking the "sound barrier" was finally removed in 1947, when the Captain Yaeger flew the Bell X-1 at a speed slightly above Mach 1 for few seconds, producing the famous and long-awaited sonic boom (caused by an impulsive pressure change created by the sonic waves detaching from the aircraft), music for the scientists attending that historical moment, but current nightmare for the 21st Century supersonic vehicles' designers [8].

The concept of motivation is what directs an individual through particular courses of actions and is what humanity is based off of. While the requirement and need for a motivation in life is significant towards having goals, succeeding in life and learning as a person, through that management differentiates individual's courses of actions from other individuals. Doris May Lessing an author for several diverse short stories, including a short story called “Flight” that demonstrates an excellent depiction of how the bond and connection between an old man and his favourite granddaughter, Alice is significant towards the perception that “letting go isn't easy for others either”. “Flight” is a short story that illustrates how strong symbolism can be to build a protagonist's character through the development of the story with the inclusion of the actions and gestures described by the way the characters within the story use self perception. Furthermore, prominent symbols include nature, birds, gates, bird cages, a beautifully described garden using distinct word choices and imagery. Motivation impacts an individual ambitions, decisions, future, personal beliefs and behaviour through the means of having a desire to fulfill a goal. Doris May Lessing used just a couple pages to develop a well written story while still incorporating the establishment of the old man that is represented through external with the addition of internal motivations by directing the protagonist towards a specific course of actions that is both educational and insightful.
