6.4 Friction 6 Newton`s Second Law of Motion
... 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. ...

... Let us consider, for instance, a rigid sphere, solid and uniform, of mass M and radius r, which is thrown horizontally along a rigid horizontal surface with an initial velocity v,. To study the motion described by the sphere we must consider two phases which are dearly different. In the first phase ...
