How do wings of airplanes can create a lift force?
Now you have the basic idea of Bernoulli's principle from the previous page, so let's talk about how it is related to the actual wings of the airplanes.

This is usual shape of the wings of airplanes from side view. As you can see, the upper side of the wing is curved upwards and has larger surface area compared to lower side. Most of wings are made to have larger surface area on upper side and it is why airplanes can get a force of lift.
When there's air flowing to wing from forehead as shown in the diagram, the air moves faster on the upper side since there are more surface area. When there is a faster movement of the air around the objects, it creates lower pressure. (Bernoulli's principle) And the object will move to where the lower pressure is, so an airplane will fly which means it can get a force of lift.
In next page, I would like to relate aerodynamics to paper airplanes since it's close to you and I want you to experience what I had said. Click here to view a next page.
