[[Torque and Rotational Dynamics]]

# Summary
* Angular displacement is measured with $\Delta \theta=\theta-\theta_0$
* Track angular displacement direction with clockwise counterclockwise sign convention
* Average angular velocity: $w_{avg}=\frac{\Delta\theta}{\Delta t}$
* Average angular acceleration: $a_{avg}=\frac{\Delta w}{\Delta t}$
* Rigid system holds shape, but different parts move at different speeds so you can't treat it as a single particle unless COM motion describes rotation well
* Slope of theta vs time shows angular velocity
* Slope of angular velocity vs time shows angular acceleration
* Integral of angular velocity vs time shows Delta theta

# Angular vs. Linear Motion
Angular motion equations are similar to linear motion equations. 
$w=w_0+at$
$\theta=\theta_0+w_0t+\frac{1}{2}at^2$
$w^2=w^2_0+2a(\theta - \theta_0)$
