Gravitational Forces Between Objects

Which of the following data would support the claim that the gravitational force between objects depends on mass?

• An object's weight can change depending on where it is on Earth.

• Further away a planet is from the sun the smaller the gravitational force.

• Gravitational force is stronger on more massive planets.

• A rocket can escape Earth's gravity by traveling at high speed.

Which of the following statements best describes the gravitational force between two objects?

• It is always attractive and depends on the masses of the objects and the distance between them.

• It is always repulsive and depends on the masses of the objects and the distance between them.

• It is always attractive and depends only on the distance between the objects.

• It is always repulsive and depends only on the masses of the objects.
