Keplers third law may be obtained from the gravitational force law equated to Newtons 2nd law and replacing the acceleraion by that of a centripetal type. The speed may then replaced by the circumference over the period. We ovatain the ratio of (distance)3 and (Period)2 How does this method outlined above express or represent keplers third law? The escape velocity may be obtained by converting all the gravitational potential energy to kinetic energy. This is a factor of sqrt(2) larger than the orbital speed. Was the approach valid? Justify the obtained relationship.
