# What is the definition of aerodynamics?

Aerodynamics is defined as a branch of mechanics dealing with air and other gases in motion and the related motion's effects on bodies in the medium. The word has a Greek origin dating back to 1837.

Closely related to aerodynamics, aerostatics is the study of different gases and the effects of the forces on bodies passing through air. Aerodynamics is particularly a focal point in the design of airplanes and automobiles. An aerodynamically designed vehicle is able to lessen the friction caused by air. Aerodynamics also involves the effects that air has on buildings and other stationary objects. Related forms of the word include aerodynamical, an adjective, and aerodynamically, an adverb.
