What Do You Know About Aerodynamics?

Aerodynamics is the study of the motion of airborne objects. It is concerned with the forces that are in support as well as forces that are against this motion. This scientific field is closely related to fluid dynamics and gas dynamics. The following questions tests your familiarity with aerospace engineering. Ace it!
