2 Mechanical rotation Newton’s Laws (applied to rotation) Every body persists in a state of uniform (angular) motion, except insofar as it may be compelled by torque to change that state. The time rate of change of angular momentum is equal to the torque producing it. To every action there is an equal and opposite reaction. (Principia Philosophiae, 1686, Isaac Newton)

3 Quantities and SI Units “F-L-T” system Define F: force [N] Define L: length [m] Define T: time [s] Derive T: torque (moment) [N-m] M: mass [kg] w: angular velocity [rad/s] J: mass moment of inertia [kg-m^2]
