Question

Explain Kepler's laws

Answer 1

Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

Answer 2

Kepler's three laws of planetary motion are:

The 1st law is that planets move around the Sun in elliptical orbits. An ellipse is a shape that resembles a flattened circle. The 2nd law is the speed of the planet increases as it nears the sun and decreases as it recedes from the sun. The 3rd law is the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
