Circular motion (AQA A-Level Physics): Flashcards

Velocity (including direction) is constantly changing

Inward force keeping object moving in circle

Acceleration directed toward centre of circular path

$\omega = \frac{v}{r}$

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

Angle when arc length equals radius

$2\pi$ radians

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

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

Multiply by $\frac{\pi}{180}$
