## BIG IDEAS
- The rate of change of [[angular velocity]] with [[time]].
- Angular acceleration represents how quickly an object speeds up or slows down its rotation.
- Symbol $\alpha$
- Measured in radians per second squared ($\frac{rad}{s^2}$)
---
### Formula
$\alpha \ = \ \frac{\Delta \omega}{\Delta t} \tag{1}$
where
$\alpha$ is angular acceleration,
$\Delta \omega$ is the change in angular velocity, and
$\Delta t$ is the change in time.
