The world today requires multiple modes of transportation, especially over the Atlantic Ocean. During and before 1900, transatlantic travel was very common and was done primarily via boats. However, due to the revolutionary change of the Wright brothers in 1903, the creation of propeller planes made possible a shorter travel time between countries. As technology developed, transportation of goods and passengers via airplanes became easier and more efficient with the replacement of jet engines in July 16, 1949, by famous inventor Frank Whittle (FindtheData, n.d.). The principles underlying the operation of a jet aircraft are associated with many laws of physics, from Newton's law of inertia to the third law of motion. These laws are also applicable to the airfoil and engines from an aerodynamic point of view, in particular with the four forces: lift, drag, weight and thrust that allow an aircraft to maneuver in the skies. First, in 1687, Sir Isaac Newton discovered three different laws of motion. (Pople, S. 2010) If there is no action of external force on an object, it, if stationary, will remain stationary, however, if it moves, it will remain in this state at a constant speed within a straight line. This is also known as the law of inertia. This law applies during flight when thrust and drag are equal, the airplane will maintain a constant speed in a straight line. If the thrust increases, the resistance and speed will also increase. Once they are equal again, the plane will no longer accelerate, but will maintain a higher and more constant speed. (NASA, nd) Another law would be the link between the resulting force acting, the mass and the acceleration produced, where it is described as F=ma (Result...... middle of paper ...... ieved December 3, 2013, from http://csep10.phys.utk.edu/astr161/lect/history/newton3laws.htmlThe Naked Scientists (n.d.).
