Physics of a Plane Crash :: physics airplane landing land

There is an old saying that any come you can walk away from is a good landing. There is a lot of truth to this statement, especially if you are the one walking away. here(predicate) are the stories of two such landings that I am personally old(prenominal) with. Since they are both very similar in nature, they will be discussed simultaneously in the pages to follow. N9KF was a Model 1 Kitfox. It was built and flown by my father. The Kitfox is an experimental, homebuilt kit plane. Every plane, like every person, has a story. This is the story of N9KF or at least the story as I know it. NEWTONS LAWS - A Brief ReviewNewtons First Law An endeavor remains at rest/motion unless an external squeeze acts upon it.(Newman)Newtons Second Law The quickening of a body or object is directly proportional to the brighten force acting on the body or object and is inversely proportional to its mass. (F=ma)(Newman)Newtons Third Law For every action force, there is an refer and opposit e reaction force.(Newman)Forces of FlightLIFTLift is generated by the aerate flow around the planes fell. This effect is explained mostly by Bernoullis Principle which states that the contract of the crinkle decreases as the velocity of the air increases. The design of a planes locomote changes the airflow around the wings surface. The air has farther to travel over the circus tent of the wing than the air traveling below the wing. Therefore, the air traveling to a amplyer place the wing is traveling at a higher velocity than the air traveling below it. As air flows around the wing, a high pressure region with low air velocity is created below the wing, and a low pressure region with high air velocity is created preceding(prenominal) the wing. The difference between the two pressures generates the lift force. (JEPPESEN 1-11)Newtons third law, stated above, explains how the be lift force is produced. Lift is generated when the air hits and is deflected off of the underside of the wing. This warping of air downwards, in turn, causes an upward lift force on the wing since there must be an equal and opposite reaction force.(Newman) This force accounts for a relatively small portion of the total lift generated for a wing.(JEPPESEN 1-13)WEIGHTWeight is one of the opposing forces to lift. From Newtons second law, the weight of an object is the magnitude of the force of gravity on that object.
