This demonstration targets a secondary school audience. It will attempt to explain the basics of the theory of flight. The pressure differential that causes lift will be attributed to Bernoulli’s Principle and Newton’s Second Law. Illustration of these principles will be accomplished by demonstrating their effects and explaining how they play a role with respect to the operation of aircraft and the Theory of Flight. Since airplanes are a familiar sight to all students, explaining how simple air is capable of supporting a heavy plane should help catch their attention and give context to the new ideas presented.
This is an introduction to the physics of fluids, presented in a manner that is both interesting and in a way that the students can relate to. Basic fluids, including Bernoulli's Principle, was once part of the high school physics curriculum but was removed recently. Fluid mechanics is a vital part of physics as it affects every moving object that is not in a vacuum.
Theory of flight incorporates basic
fluid mechanics. This project will look at pressure differentials in a
fluid, for simplicity it will be assumed that the air is incompressible.
This incorporates Newton's Second Law, which the students will have learnt
in the regular high school curriculum. It will also look at a moving fluid
and its behavior with respect to pressure (Bernoulli's Principle).
