Kepler’s law of areas, relates to

Correct option is C

Correct Answer: (c) Conservation of angular momentum
Explanation
· Kepler’s Second Law (Law of Areas) states that a planet sweeps out equal areas in equal intervals of time as it orbits the Sun.
· This happens because the angular momentum of the planet remains conserved when no external torque acts on it.
Information Booster
· When a planet comes closer to the Sun, it moves faster; when it is farther, it moves slower, but the area swept per unit time remains constant.
Additional Knowledge
· Kepler’s First Law → Planets move in elliptical orbits.
· Kepler’s Third Law → T²∝R³ (square of time period ∝ cube of mean distance).
