Question

explain what is kepler's law

Answer 1

Answer:

Kepler's Laws of planetary motion: Kepler derived three laws which govern the motion of planets around the sun. These are:  

(i) The orbit of a planet is an ellipse with the sun at one of the foci.

(ii) The line joining the planet and the sun sweep equal area in equal intervals of time.

(iii) The cube of the mean distance of a planet from the sun is proportional to the square of its orbital period.

                 r^3/T^2 = constant

Answer 2

Answer:

Johannes Kepler undertook when he formulated his three laws of planetary motion.

Explanation:

There are actually 3, Kepler's laws that is, of planetary motion:

1) Every planet's orbit is an ellipse with the Sun at a focus.

2) A line joining the Sun and a planet sweeps out equal areas in equal times. (Kepler's 2nd law of planetary motion, aka the law of areas)

3) The square of a planet's orbital period is proportional to the cube of the semi-major axis of its orbit. As it’s the third which is most often used, Kepler’s law usually means Kepler’s third law (of planetary motion).
