Math in Aviation - Essay Example Drag is the normal friction caused by the plane moving through air molecules. Drag is also a reaction to lift and this lift must be generated by the wings of the airplane in flight. Newton's First Law of Motion: An object at rest will remain at rest or an object in motion will continue in motion at the same speed and in the same direction, until an outside force acts on it. For an aircraft to taxi or fly, a force must be applied to it. It would remain at rest without an outside force. Once the aircraft is moving, another force must act on it to bring it to a stop. It would continue in motion without an outside force. This willingness of an object to remain at rest or to continue in motion is referred to as inertia. Newton's Second Law of Motion: If a object moving with uniform speed is acted upon by an external force, acceleration will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved. The motion will take place in the direction in which the force acts. Simply stated, this means that an object being pushed by 100 pounds of force will travel faster than it would if it were pushed by 50 pounds of force. A heavier object will accelerate more slowly than a lighter object when an equal force is applied. Newton's Third L Newton's Third Law of Motion: For every action (force) there is an equal and opposite reaction (force). This law can be demonstrated with a balloon. If you inflate a balloon with air and release it without securing the neck, as the air is expelled the balloon moves in the opposite direction of the air rushing out of it. Bernoulli's Principle: When a fluid flowing through a tube reaches a constriction or narrowing of the tube, the speed of the fluid passing through the constriction is increased and its pressure is decreased. Lift: The lift force of a wing is derived from the independent action of its upper and lower surface. Aerodynamics is the study of the forces that let an aircraft fly. Motion is changing place or position. Air has no force or power other than pressure when it's motionless. When air is moving, its force becomes apparent. A moving object in motionless air has a force exerted on it as a result of its own motion. It makes no difference in the effect whether an object is moving in relation to the air or the air is moving in relation to the object. Newton's first and third Laws of Motion explain why deflecting the air downwards must result in a corresponding upward force. The air moving over the upper surface of the airplane is forced too travel farther, therefore velocity is increased. The increase in velocity caused a decrease in pressure. This causes lift in the upper surfaces. The air that passes beneath the airfoil has less distance to travel, this results in increase in air pressure on the lower surfaces and in decrease in air pressure on the upper surfaces. The total lift produced by the airfoil is equal to the difference downwards. The wing is said to have a relative angle of attack. The lift drops off at high angles of attack because the air instead of flowing smoothly over the upper surface breaks away from it and forms eddying currents. Gravity: Gravity is natural force acting upon the airplane. Gravity is the force that plays an
