6 Newton`s Second Law of Motion–Force and
... Both liquids and gases are called fluids because they flow. • Fluid friction occurs as an object pushes aside the fluid it is moving through. • The friction of liquids is appreciable, even at low speeds. • Air resistance is the friction acting on something moving through air. ...

The problem becomes therefore how to modify the Newton’s laws so that they become still applicable in a rotating frame. Since the ...
