... Air resistance / Drag When an object moves through air or any other fluid, the fluid exerts a friction-like force on the moving object. The force is called drag. Drag depends upon the speed of the object, becoming larger as the speed increases. (UNLIKE FRICTION!) Drag also depends upon the siz ...
