a=v^2/r is the equation for the normal component of acceleration
a=GM/r^2 derived from F= GMm/r^2
a satellite orbiting the Earth only has a normal component of acceleration correct ?
I have a homework problem that involves the equation v=sqrt((g*R^2)/r) I am confused as to where this equation comes from. I know that Vcirc = sqrt((GM)/r) and Vesc = sqrt((2GM)/r)
