Question

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

Answer 1

Hi....

1)The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus. ...

2)The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.

3) The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.


Hope this helps u!!

Answer 2

Hey 2nd time I am giving answer of this question
Kepler's three laws of planetary motion
1)Law of orbits:- Every planet revolves in an elliptical orbit around the sun with the sun at one of the foci

2) Law of areas:- The line joining the centre of the sun to the centre of the planet i.e. radius vector sweeps out equal areas in equal intervals of time.


3)Law of periods :- Square of the time period of revolution of the planet around the sun is directly proportional to the cube of semi major axis of elliptical orbit
i.e.
