Question

* (4) Write the three laws given by Kepler
How did they help Newton to arrive at the
inverse square law of gravity?​

Answer 1

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; and 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).
