Newton's law of gravitational force is expressed as follows:
a. An object with no force on it moves in a straight line with constant velocity. b. An object with a force on it is accelerated in the direction of the force an amount inversely proportional to its mass and directly proportional to the size of the force. c. For every action there is an equal and opposite reaction. d. The force between two objects is directly proportional to the product of their masses and inversely proportional to the distance between them squared.
