In my class, we developed a list of formulas for circular orbits. One of them is E/m=1/2v(adsbygoogle = window.adsbygoogle || []).push({}); ^{2}-GM/r=constant. To derive escape velocity we find for what v does E=0. But an orbit of this nature is certainly not circular! How can we apply the formula?
