Drag physics meaning
WebMeaning of drag (physics). What does drag (physics) mean? Information and translations of drag (physics) in the most comprehensive dictionary definitions resource on the web. WebJun 4, 2011 · 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. Aerodynamics even acts on cars, since air flows around cars.
