This diagram of aerodynamics illustrates the study of how gases interact with moving bodies. Because air is the most common gas we encounter, aerodynamics primarily concerns the drag and lift forces caused by air passing over and around solid bodies. Aerodynamic principles are used in the design of many things, including buildings, bridges, and even soccer balls; however, the aerodynamics of aircraft and automobiles are of primary concern. Aerodynamics is used in the study of flight and the science of building and operating aircraft, known as aeronautics. Aeronautical engineers use aerodynamics fundamentals to design aircraft that fly through the Earth's atmosphere, as illustrated in this aerodynamics illustration diagram.
