The Ultimate Trivia Quiz On Aerodynamics
Objects launched into the air interacts with the air and obey some aerodynamic principles. Aerodynamics is therefore the study of the motion of such objects in the air. It is associated with gas mechanics and fluid mechanics. Certain objects like aircrafts obey the principles of aerodynamics. Do you know any other? Let's take a quiz!
