Detailed explanation-1: -EXPLANATION: Kepler’s second law of planetary motion deal with the area swept by a planet in different intervals of time. The planet sweeps equal areas in equal intervals of time.
Detailed explanation-2: -Kepler’s Second Law Describes the Way an Object’s Speed Varies along Its Orbit. A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves.
Detailed explanation-3: -The second law (Law of areas): The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time.
Detailed explanation-4: -Kepler’s 2nd Law of Areas: The line joining a planet to the Sun sweeps out equal areas in equal interval of time. The rate of change of area with time will be constant. We can see in the above figure, the Sun is located at the focus and the planets revolve around the Sun.
