MCQs on Kepler's Law for NEET 2021
Kepler’s law explains the motions of planets in the solar system.
Kepler’s First Law: All the planets move around the sun in elliptical orbits with the sun at the focus.
Kepler’s Second Law: The line joining the planet to the sun sweeps out equal areas in an equal interval of time.
ΔA is the area swept
Δt is the time interval
Kepler’s Third Law: This law states that the square of the time period (P) is directly proportional to the cube of the semi-major axis of its orbit.
P2 ∝ a3
