Which statement is true?

• Gravity is the force of attraction between two objects with mass and is dependent on the distance between these objects.

• Gravity is the force that repels two objects that have opposite charges. It is dependent upon the charges of the objects.

• Gravity is a force that keeps objects moving in space. The less the object weighs, the further out in space gravity will pull the object.

• Gravity is the force of resistance to a change in position. The greater the distance between two objects, the greater this force will be.
