Kinematics of Circular Motion 2 (AQA A-Level Further Maths): Flashcards

$v = romega$

$a = romega^2 = \frac{v^2}{r}$

Towards the centre

$F = mr\omega^2 = \frac{mv^2}{r}$

Towards the centre

Resultant force required to maintain circular motion

$T = \frac{2\pi}{\omega}$

Velocity changes direction continuously

$\mathbf{a} = -\omega^2\mathbf{r}$

Centre-seeking
