## anonymous one year ago Please help me on this question! I'm so lost I've looked in all my notes! how does an increase in orbital radius effect average orbital speed?

if you are talking about planets, orbital speed is something like: $V_o \approx \sqrt{\frac{GM}{r}}$ so what would happen to Vo if you increase r ?

I don't know that's where I'm confused
