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. ...

Moment of Inertia - Ryerson Department of Physics
... A heavy flywheel is set in rotation by a mass attached to a string wrapped around the axle of the flywheel. The force exerted by the falling mass is related to the torque, Γ, and the rate of change of angular velocity of the wheel, that is, the angular acceleration, α. The moment of inertia, I, is t ...
