Normal Airflow Over a Wing Example

The image above shows how air flows over both the bottom and the top of the airfoil.
You can clearly see how the air flowing over the top of the airfoil is moving faster than the air going underneath.

Its the acceleration of the air flowing over the top that causes its pressure to drop which in turn causes lift to be produced.

It must be understood that this example of how lift is created is only the tip of the iceberg and the there are volumes of material written on this subject that describe the production of lift from different points of view and in great detail.

Understanding the image above will help you at the private pilot level, leave the more complex physics equations to the designers.
