Aerodynamics is the study of the motions and forces of gases on an object. It aids in the design of airplanes, sailboats, trains, cars, and other objects moving quickly through the air as well as buildings, bridges, and windmills affected by the wind moving past them.
The fact that air can create a force strong enough to support an airplane in flight is sometimes difficult to imagine. When we walk through air, we don't really feel anything, unless there is a wind! Then we feel the force that the air makes on us. Yet, even when there is no wind and we can not feel the air, it does exert a force on objects.
