**Chapter 6 ****Curved and Rotational Motion**

**ROTATIONAL DYNAMICS**

The dynamics of translational motion involve describing the acceleration of an object in terms of its mass (inertia) and the forces that act on it: **F**_{net} = *m***a**. The dynamics of rotational motion involve describing the angular (rotational) acceleration of an object in terms of its **rotational inertia**and the **torques** that act on it.
