Question

Write the three laws given by Kepler.
How did they help Newton to arrive at the
inverse square law of gravity?

Answer 1

Explanation:

First law states that every planet's orbit is an ellipse with the sun at a focus

Second law states that the line joining the sun and a planet sweeps out equal are in equal time

Third law the square of planets orbital period is proportional to the cube of the semi major axis of its orbits

Answer 2

Answer:

Kepler's law apply :first law: planetery orbits are elliptical with the sun at a focus. Second law :the radius vector from the sun to a planets equal areas in equal times. Third law : the ratio of the square of period of revolution and the cube of the ellipse semi major axis is the same for all planets.
