How does Newton's Universal Law of Gravitation explain Kepler's laws?
A)Universal gravitation implies that the orbits of the planets must be elliptical (Kepler's firstlaw).
B)Universal gravitation implies that the planets will sweep out equal areas in equal times(Kepler's second law).
C)Universal gravitation implies that the planets further from the Sun will move more slowlythan the planets closer to the Sun (Kepler's third law).
D)Universal gravitation implies that when a planet is closer to the Sun in its orbit, it will movefaster than when it is farther from the Sun (Kepler's second law).
E)Both C and D are correct.

Universal gravitation explains both Kepler's third law, which states that planets further from the Sun will move more slowly, and Kepler's second law, which states that a planet will move faster when it is closer to the Sun in its orbit. The Universal Law of Gravitation explains both Kepler's third law (planets further from the Sun move more slowly) and Kepler's second law (when a planet is closer to the Sun, it will move faster in its orbit) as the force of gravity between the Sun and each planet decreases with distance.
