# Angular Motion

This post is part of the HSC Physics Syllabus Module 5: Advanced Mechanics.

Let’s learn to solve problems, model and make quantitative predictions about objects executing uniform circular motion in a variety of situations. In particular, we’re going to look at:

• Angular motion

### Angular speed and velocity

Angular displacement is denoted using \theta.

Angular speed is given by the following:

\omgega = \frac{d \theta}{dt}

### Angular motion

Angular displacement is denoted using: \theta.

Angular displacement is denoted using: \omega.

Angular acceleration is given by the following:

\alpha= \frac{d \omega}{dt}

So our motion equations become:

\omega= \omega_o + \alpha t \theta= \omega_o t + \frac{1}{2}\alpha t^2 \omega^2= \omega_0^2 + 2 \alpha \theta
