Science World Resources: Lift

Ever wonder about the physics of lift? Join Brian and Christina as they explore Bernoulli's principle, the phenomena that helps flying things fly!

Bernoulli’s principle states that as the speed of air increases, the pressure decreases. This principle is partially responsible for the ability of an airplane to lift off the ground. When an airplane moves through the air, the wings push against the air, so that the airflow is slower under the wing than above it. As a result, Bernoulli’s principle tells us that there will be more pressure on the bottom of the wing than on the top. The slow, high pressure air underneath the wing creates lift.
