Which statements are true concerning newton's law of gravitation? the gravitational force is related to the mass of each object. the gravitational force on a satellite is less at an altitude of 500 km above the earth than at an altitude of 1000 km. a large and a small object are gravitationally attracted to each other. the magnitude of the gravitational force on the larger object is greater than on the smaller. the gravitational force is an attractive force. the gravitational force between the earth and a person is constant, no matter how high the person is above the surface of the earth.
