Lift: Looking to the Skies - Lesson 2

Have you ever wondered about the forces that keep airplanes up in the air? In this lesson, we will explore what generates the lift force that keeps airplanes flying.

We can get an even better understanding of lift and how it works by performing another experiment. When engineers want to study the aerodynamic properties of a body, they use a wind tunnel. They analyze how the air moving through the wind tunnel passes over the body and generates the forces acting on it. In the following experiment, we will use a reproduction of a small wind tunnel to test the performance of a simple shape and understand the effect of lift on an airplane wing.
