Contact Force and Non-Contact Force

As distance between two objects increase the pull of gravity 

• Increases
• Decreases

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
