Newton's view, for which there is considerable doubt, is that he had at hand all the information to consider a thought experiment in which the same gravitational force that pulls a falling apple to the ground could be the same force that holds the moon in orbit around the earth.

Newton showed that the gravitational force on a body of mass m from a spherically symmetric body of total mass M whose center is located a distance r away is equivalent to the force on m from a point mass M located a distance r away.

; What is the Gravitational Force? This is NOT a force of CONTACT. Any object on the Earth or at least close to Earth, will experience a gravitational force. For example, when one shoots a basketball, the force of gravity acts to pull the ball back to the floor.

Weight and the Gravitational Force ... Then, the orbit of the Moon about the Earth could be a consequence of the gravitational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.

The strength of the gravitational force between two bodies depends on their mutual distances; the larger the distance, the smaller the force. Furthermore, it is dependent of the mass of the two objects; the greater the mass the larger the gravitational force.
