A. First Law
B. Second Law✓ Correct Answer
C. Third Law
D. Law of Gravitation
💡 Solution & Explanation
Kepler's Second Law of planetary motion establishes that a planet moves faster when closer to the Sun and slower when farther away, sweeping out equal areas in equal time intervals. The First Law describes elliptical orbits, and the Third Law relates the orbital period to the semi-major axis.
