The universal gravitation equation thus takes the form. More on Newtons Law of Universal Gravitation Prehistoric man realized a long time ago that when objects are released near the surface of the Earth they always fall down to the ground. The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points and this force is proportional to the masses of the objects and inversely proportional to their separation This attractive force always points inward from one point to the other.
The precise value of G was determined experimentally by Henry Cavendish in the century after Newtons death.
The value of G varies witha height above the earths surfaceb depth below the groundc radius of the planetd None. This law helps calculate the force of gravity dependent on the mass of the objects and the distance between them. He could explain this by postulating that a. A law stating that any two masses attract each other with a force equal to a constant called the gravitational constant multiplied by the product of the two masses and divided by the square of the distance between them.
