7.2Dynamics of Rotational Motion


In the previous tutorial "Kinematics of Rotational Motion", we explained that there is a close analogy between linear and rotational quantities both in concept and in formulae. Logically, this analogy must extend in the Dynamics-related quantities as well. Therefore, in this tutorial we will explain Dynamics of Rotational Motion relying on Dynamics of Linear Motion, obviously making the proper arrangements to fit the current topic. Hence, let's discuss all dynamic quantities of rotational motion one by one.
