<aside> 🌀 Uniform circular motion: the motion of an object with a constant speed along a circular path of constant radius

</aside>

<aside> 🔄 Centripetal acceleration $(\overrightarrow{a}_c)$: the instantaneous acceleration that is directed toward the centre of a circular path

There are 3 equations used:

$a_c = \frac{v^2}{r}$; $a_c = \frac{4\pi^2r}{T^2}$; $a_c = 4\pi^2rf^2$

where r is the radius, T is the period (in seconds), and f is the frequency (in Hz)

</aside>

• period can also be found using $T=\frac{1}{f}$
