As the distance between two objects increases, the pull of gravity...

• Increases

• Decreases

• Stays the same

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity
