Question 1:

Who formulated the three laws of planetary motion?

Explanation: Johannes Kepler formulated the three laws of planetary motion based on the observations made by Tycho Brahe.

Question 2:

What is Kepler's first law of planetary motion?

Explanation: Kepler's first law states that the planets move in elliptical orbits with the Sun at one focus.

Question 3:

What is Kepler's second law of planetary motion?

Explanation: Kepler's second law states that the planets move at varying speeds along their orbits, sweeping out equal areas in equal times.

Question 4:

What is Kepler's third law of planetary motion?

Explanation: Kepler's third law states that the square of the orbital period of a planet is proportional to the cube of its semi-major axis.

Question 5:

Which law of planetary motion explains the concept of equal areas in equal times?

Explanation: Kepler's second law of planetary motion explains the concept of equal areas in equal times, stating that planets sweep out equal areas in their orbits in equal time intervals.
