Rotational dynamics (AQA A-Level Physics): Flashcards

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

rad s⁻¹ (radians per second)

Angle when arc length equals the radius

$2\pi$ radians

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

$v = r\omega$

Increases with distance from centre

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

rad s⁻² (radians per second squared)

$a = r\alpha$
