Home » Gravity Gravity 1 The hypothesis of matter's being at first evenly spread through the heavens is, in my opinion, inconsistent with the hypothesis of innate gravity without a supernatural power to reconcile them, and therefore, it infers a deity. Isaac Newton Power, Gravity, Opinion Add to Collection 2 The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit. Isaac Newton Moon, Earth, Gravity Add to Collection 3 The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity. Isaac Newton Law, Body, Gravity Add to Collection 4 Gravity must be caused by an Agent acting constantly according to certain laws, but whether this Agent be material or immaterial I have left to the consideration of my readers. Isaac Newton Acting, Gravity, Left Add to Collection 5 Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force. Isaac Newton Sun, Motion, Gravity Add to Collection 6 I have explained the phenomena of the heavens and of our sea by the force of gravity, but I have not yet assigned a cause to gravity. Isaac Newton Sea, Gravity, Force Add to Collection 7 If a projectile were deprived of the force of gravity, it would not be deflected toward the earth but would go off in a straight line into the heavens and do so with uniform motion, provided that the resistance of the air were removed.
