The world today requires multiple ways of transport, especially over the Atlantic Ocean. During and before the 1900’s, transatlantic travels were very common and are mainly carried out via boats. However, due to the revolutionary change by the Wright brothers, in 1903, the creation of the propeller planes made shorter travel time between one country to another possible. As technology develops, the transportation of cargo and passengers via airplanes became easier and more efficient with the replacement of jet engines in July 16, 1949, by the famous inventor Frank Whittle (FindtheData, n.d.). The principles behind how a jet-engine powered aircraft works associate with many laws of physics, from Newton’s Law of Inertia to the Third Law of Motion. These laws are also applicable to the aerofoil and the engines aerodynamically, in particular with the four forces: lift, drag, weight and thrust which allows an aircraft to maneuver across the skies.
Firstly, back in 1687, Sir Isaac Newton discovered three different laws of motion. (Pople, S. 2010) If there is no external force action upon an object, it will, if stationary, remain stationary, however, if moving, it will remain in this state at a steady speed within a straight line. This is also known as the law of inertia. This law applies during a flight when the thrust and drag are equal, the aircraft will hold a steady speed tracking in a straight line. If the thrust increases, the drag and the airspeed will increase as well. Once they are equal again, the aircraft will not accelerate anymore, but holds a higher and steady airspeed. (NASA, n.d.) Another law would be the link between the resultant force acting, the mass and the acceleration produced, where it is described as F=ma (Result...

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.
Major Ted Tolman’s F-105 Thud fighter/bomber streaked through the air at just under the speed of sound. His aircraft performed modestly at best, struggling to maintain its speed and altitude under the heavy load of ordinance and fuel it carried under its wings (Patrick).

Following World War II and the jet engine technology that emerged largely toward its end, aerospace engineers knew well that the technology had great potential for use in the commercial aviation industry. The Comet was the first aircraft to utilize jet propulsion; however, its designers failed to consider the metallurgy of the aircraft’s materials under flight conditions or the consequences of their atypical window design. The aircraft was designed by Britain’s De Havilland Aircraft Company and entered service in May 1952. After a year of service, however, the design issues mentioned above resulted in the failure of several Comet aircraft. Extensive evaluations revealed that repeated pressurization stress on the aircraft’s main cabin had caused its structure to fail.
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
This edu website describes how the impact of invention of the airplane by the wright brothers created a new world of technology. It proves my thesis because it explains how commercial & potential of aviation came to being because of the wright brothers. This is a secondary source because it draws conclusions from primary sources and because it's a review of what happen and what came into being.

Flight is one of the most important achievements of mankind. We owe this achievement to the invention of the airfoil and understanding the physics that allow it to lift enormous weights into the sky.
Driving has been around for just over 100 years, but the first thoughts of physics has been around since 400 BC (to be edited ). Driving safety implications have been discussed and improved over the decades as technology begins to leap ahead of its time. According to physician; Newton, there are three laws of motion that is now used in everyday life to try and help prevent deaths due to driving implications. The first law is “An object at rest will remain at rest unless acted upon on by an unbalanced force.” The object, or Car is in motion continues its motion with the same speed and in the same direction unless acted upon by an unbalanced force. The second law is “Acceleration is produced when a force acts on a mass.” While the third Law of Motion is : “ For every action there is an equal and opposite re-action.This means that for every force there is a reaction force that is equal in size, but opposite in direction.”
Bottle rockets are great models to examine Newton’s three laws of motion. The bottle rocket will remain on the ground until an unbalanced force, water, thrusts the rocket upward. This is defined by Newton’s first law of motion: an object at rest stays at rest or an object in motion, stays in motion (in the same direction/at the same speed) unless acted upon by an unbalanced force. It is also known as the law of inertia.
