If Earth's mass was cut in half, what would happen to your weight?

• Increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, weight is not affected by gravitational force

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
