BERNOULLI’S PRINCIPLE
States that:
As fluid moves around an object, creates similar pressures on that object. Faster air means more pressure. The key to flight is creating pressure downwards on the wing to keep the object in the air.
Movement around an object, creates similar pressures on that object. Slower air means less pressure. The key to flight is creating pressure upwards on the wing to keep the object in the air.
