Angular velocity (omegaomegaomega) and tangential velocity (vvv)
v2r\frac{v^2}{r}rv2 or rω2r\omega^2rω2
Minimum GPE, maximum KE
Maximum GPE, minimum KE
Push (rod can push and pull; string only pulls)
umin=2gru_{\min} = 2\sqrt{gr}umin=2gr or 4gr\sqrt{4gr}4gr
umin=5gru_{\min} = \sqrt{5gr}umin=5gr
String cannot push, only pull
When normal reaction R=0R = 0R=0
To find velocities at different heights
