How do you explain Kepler's laws of planetary motion?

Answer 1

Kepler's laws of planetary motion describe the orbits of planets around the sun. The first law, the Law of Ellipses, states that planets move in elliptical orbits with the sun at one focus. The second law, the Law of Equal Areas, indicates that a line segment joining a planet and the sun sweeps out equal areas during equal intervals of time, meaning planets move faster when closer to the sun. The third law, the Law of Harmonies, relates the square of a planet's orbital period to the cube of the semi-major axis of its orbit, showing that more distant planets take longer to orbit the sun.
