圆周运动的相关公式

角速度：\(\omega = \displaystyle \frac{\mathrm{d} \theta }{\mathrm{d} t}\)

角加速度：\(\beta = \displaystyle \frac{\mathrm{d} \omega }{\mathrm{d} t} = \frac{\mathrm{d^{2}} \theta }{\mathrm{d} t^{2}}\)

而 \(\displaystyle \nu = \omega R, \quad a_n = \frac{v^2}{R} = R \omega ^2, \quad a_\iota = \frac{\mathrm{d} v}{\mathrm{d} x} R \beta\).
