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

Angular velocity ($omega$) and tangential velocity ($v$)

$\frac{v^2}{r}$ or $r\omega^2$

Minimum GPE, maximum KE

Maximum GPE, minimum KE

Push (rod can push and pull; string only pulls)

$u_{\min} = 2\sqrt{gr}$ or $\sqrt{4gr}$

$u_{\min} = \sqrt{5gr}$

String cannot push, only pull

When normal reaction $R = 0$

To find velocities at different heights
