Bernoullis Principle

• Pressure in a moving stream exerts less pressure
  than the air surrounding the moving stream

Quick stream low air pressure
Slow stream High air pressure

Bernoulli Flight

• Bernoullis Principle is what allows birds and
  planes to fly.
• The secret behind flight is under the wings.

• The air on top of the wing must travel a longer
• distance than the air below the wing. But, air
  on
• both sides must reach the end of the wing at the
• same time. Therefore, the air on top of the wing
  
• traveling faster less air pressure.

Below is a NASA illustration of what surface
pressure is exerted on what surface areas of the
wing.
