Circular Motion (HSC SSCE Physics): Flashcards

Motion along circular path at constant speed

$v = \frac{2\pi r}{T}$

Tangential (perpendicular to radius)

$a_c = \frac{v^2}{r}$

Toward the centre of the circular path

$F_c = \frac{mv^2}{r}$

Vector sum of all forces, not an additional force

$\Delta\theta = \frac{s}{r}$

$\omega = \frac{\Delta\theta}{\Delta t}$

$v = \omega r$
