... 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 size and the shape of the ...

Newton`s Laws of Motion
... Consider the flying motion of birds. A bird flies by use of its wings. The wings of a bird push air downwards. In turn, the air reacts by pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air (downwards) is opposite ...
