Bernouli’s Principle

1. Bernouli’s Principle

2. Bernouli’s Principle • The Bernoulli's Principle is the principle that allows wings to produce lift and planes and helicopters to fly.

3. Bernouli’s Principle • This principle works on the idea that as a wing passes through the air, its shape makes the air travel more over the top of the wing than beneath it.

4. Bernouli’s Principle • Fast moving air equals low air pressure while slow moving air equals high air pressure. • Fast Air = Low Pressure • Slow Air = High Pressure

5. Bernouli’s Principle

6. Bernouli’s Principle • This creates a higher pressure beneath the wing than above it.

7. Bernouli’s Principle • The pressure difference causes the wing to push upwards and lift is created
