WebIsaac Newton not only proposed that gravity was a universal force ... more than just a force that pulls objects on earth towards the earth. Newton proposed that gravity is a force of attraction between ALL objects that have mass. And the strength of the force is proportional to the product of the masses of the two objects and inversely proportional … WebExpert Answer. 222 The forec of gravity on a mass a is proportional so the mas. Near the surfket of the Farth it is a vertical forse. Bocause of this proportionality, we can write the magritale of this ficce as F = mg where, near the surface of the Earth (the "grousth), the proportionalicy constint f = 9.8mow−1 is bypically refered to as the ...
