1. How airplane fly?

2. Bernoulli Principle Slower High pressure FasterLow pressure

3. Bernoulli Principle As an airplane fly there are two types of pressure, one is above the wing and one is at the bottom. Bottom = high pressure, because the air that is at bottom moves slower than above the wing. Above= low pressure, because the air has to move faster so it reach the end of the wing at the same time as the air at the bottom.

4. How Bernoulli principle explain how airplane fly? As the Bernoulli’s principle state that the faster the air move = lower pressure Slower the air move= higher pressure And Air always wanted to go from higher pressure to lower pressure So, Lifting action occurs.
