Which of the following statements are true about gravitational force? Identify all that apply.
The gravitational force only acts between very, very massive objects.
The gravitational force acting upon an object is the same as the weight of the object.
The gravitational force between two objects is independent of the mass of the smaller of the two objects.
If object A gravitationally attracts object B with a force of X Newton, then object B will also gravitationally attract object A with the same force of X Newton.
If an object is placed two earth-radii above the surface of the earth, then the force of gravitational attraction between the object and the earth will be one-fourth the magnitude as on earth's surface.
