Law Of Action And Reaction


In the context of aviation, the Law of Action and Reaction, also known as Newton's Third Law, is a fundamental principle that governs the motion of aircraft. It states that for every action, there is an equal and opposite reaction. This law is applied in various aspects of aviation, from the basic principles of flight to the operation of jet engines. For instance, when an airplane propeller pushes air backwards, the air pushes the propeller, and therefore the airplane, forwards. This is the reaction to the action of the propeller. Similarly, in a jet engine, hot gases are expelled out of the back of the engine at high speed. The reaction to this action is the forward thrust that propels the aircraft. Understanding and applying the Law of Action and Reaction is crucial in designing, operating, and controlling aircraft, as it directly influences the aircraft's speed, direction, and altitude.
