The law of universal gravitation states that both mass and distance of objects affect the gravitational force between them. Gravitational force increases as the mass of the objects increase. Gravitational force decreases as distance between the objects increases. Why are these statements considered scientific law, and not scientific theory?

• The statements tells what happens, and not why it happens.

• The statements involve mass and distance measurements.

• The statements explain the attractive force between two objects.

• The statements predict what will happen under certain conditions.
