Question

Newton's universal law of gravitation from kepler third law of planetary motion

Answer 1

Newton's law of gravitational = this law states that in the universe is particle attract every other particle with a force of attraction that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them it is also referred as universal law of gravitation.

Answer 2

Answer:

Kepler's laws and Newton's laws taken together imply that the force that holds the planets in their orbits by continuously changing the planet's velocity so that it follows an elliptical path is

(1) directed toward the Sun from the planet,

(2) is proportional to the product of masses for the Sun and planet, and

(3) is inversely proportional to the square of the planet-Sun separation. This is precisely the form of the gravitational force, with the universal gravitational constant G as the constant of proportionality.

Thus, Newton's laws of motion, with a gravitational force used in the 2nd Law, imply Kepler's Laws, and the planets obey the same laws of motion as objects on the surface of the Earth.

Hope it helps you :)
