Laws governing rotational motion
In this chapter, we have focused on translational motion, when the object being considered changes its position. But what if an object rotates about a center or (if it’s an extended object) revolves on itself about some axis?
It turns out that analogous principles for rotational kinematics, dynamics, and conservation principles exist. For example, the analog of Newton’s laws of motion can be wriiten down for rotational motion. Analogous to momentum, there is a quantity called angular momentum and it is also conserved.
We’ll look at rotational mechanics in Chapters 9 and 13.
