newtonian mechanics - A simple explanation of Kepler's Third Law ...
2016年3月21日 · Kepler's third law is much stronger than its restriction to circular orbits - it also states that the period of an elliptical orbit only depends on its major axis and is independent of …
Kepler's Third Law - average radius instead of semimajor axis?
2021年10月13日 · But you can't really call that the "average radius of an orbit" By Kepler's second law, any object on an elliptical orbit will spend more than half its period traversing the half-orbit …
Kepler's third law doesn't give earth's orbital period! Why?
Kepler's 3rd law assumes that the Earth travels in a perfect ellipse with the only gravitational force on it being from the Sun. Further, Kepler's laws are derived from Newtonian gravitation. In …
