Which of the following physical laws states that the line joining a planet and the Sun sweeps out equal areas in equal intervals of time?

💡 Solution & Explanation

Kepler's Second Law describes how planets move faster when closer to the Sun and slower when farther away, sweeping out equal areas in equal times, driven by conservation of angular momentum. The first law deals with elliptical orbits, and the third relates orbital period to semi-major axis distance. These laws apply universally to orbiting bodies in astrophysics.
