... Kepler's Laws . ... Second Law . 12a. More on 2nd Law . ... Kepler's 2nd law prescribes the way the velocity V of an object orbiting a single center varies around its orbit: . The rate at which the line to the center ("radius vector") covers area does not change around the orbit." As noted in section #12 , this means that the object's velocity V increases when its distance r decreases, and vice versa. ... Because by Kepler's 2nd law, the Earth moves in its orbit a little faster in winter. ...
