Basic Principles Of Aerodynamics! Quiz - Quiz

Solid objects like airplanes and birds fly perfectly in the air because they obey the laws of aerodynamics. Do you already know this? Aerodynamics is a new knowledge of the interaction between solid objects flying and the air. This scientific concept is closely associated with fluid mechanics and gas mechanics. Let's take a quiz!
