Gravitation

07 Gravitation

This great scientist stated that in the universe each particle of matter attaract every other particle. He postulated “The force of attaraction between any two material particles is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them” It act along the line joining the two particles.” This universal law of gravitation was given by
