Rotational Kinematics

Core Sentence / 核心句

Rotational kinematics describes orientation through angular position, velocity, and acceleration.
$\omega =\frac{d\theta }{dt},\alpha =\frac{d\omega }{dt}$
$s=r\theta ,v_t=r\omega ,a_t=r\alpha$

Watch Out / 易错点

同一刚体各点的 $\omega$ 相同，但 tangential speed 随 $r$ 改变。
