B.1. Rigid Bodies and Rotational Dynamics

In Section 6.1 we looked at motion in a circle, but exclusively at objects moving at constant speed round a circle. We understood the idea that even though their speed is constant, they are accelerating because there is a resultant centripetal force acting. Now, we will build upon these ideas to look at objects that are not travelling at a constant speed - i.e. they have an angular acceleration. Most of the stuff we look at has analogues with some of the linear motion stuff we looked at tin the beginning. For example, we have angular suvat equations, we have angular momentum, we have rotational equilibrium and angular equivalents of Newton's laws.
