Gravity

A student claims that the gravitational force between two objects depends upon the mass of the objects and the distance between them. Which argument best supports the student's claim?

• If the distance between two objects increases, the gravitational force between the objects will decrease.

• If the distance between two objects decreases, the gravitational force between the objects will disappear.

• If the distance between two objects increases, the gravitational force between the objects will increase.

• If the distance between two objects decreases, the gravitational force between the objects will not change.

• If Earth were much bigger, the gravitational force between Earth and the Moon would not change.

• If Earth were much bigger, the gravitational force between Earth and the Moon would disappear.
