Bernouli’s Principle

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

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.

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

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

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