Detailed explanation-1: -Aerodynamics is the way air moves around things. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air reacts to aerodynamics. A rocket blasting off the launch pad and a kite in the sky react to aerodynamics.

Detailed explanation-2: -Aerodynamics comes into play in the study of flight and the science of building and operating an aircraft, which is called aeronautics. Aeronautical engineers use the fundamentals of aerodynamics to design aircraft that fly through the Earth’s atmosphere.

Detailed explanation-3: -The word aerodynamics has been around since the mid-1800s, combining the Greek prefix aero-, “air, ” and dynamics, a word applied to many branches of physics, from the Greek dynamikos, “powerful."

Detailed explanation-4: -According to the theory of aerodynamics, a flow is considered to be compressible if the density changes along a streamline. This means that – unlike incompressible flow – changes in density are considered. In general, this is the case where the Mach number in part or all of the flow exceeds 0.3.

Detailed explanation-5: -In fluid mechanics, an aerodynamic force is a force exerted on a body by the air (or other gas) in which the body is immersed, and is due to the relative motion between the body and the gas.
