Circular motion

Let us consider an object rotating about a fixed axis, as in the figure below.

**Figure 5.1:** Motion of a body about a fixed axis
$\begin{figure} \begin{center} \leavevmode \epsfysize=6 cm \epsfbox{figs/rotate-1.eps}\end{center} \end{figure}$

When we discussed linear and projectile motion, we introduced three measures of such motion: the distance, velocity, and acceleration. For circular motion we can define analogous quantities.

Angular position
Angular velocity
Angular acceleration
