• True
• It depends

Any object with mass has gravity.

• True
• Sometimes
• False
• Never

As distance between two objects increase the pull of gravity 

• Increases
• Decreases
• Stays the same

The force of gravity acting on an object is the object's ______.

• mass
• matter
• weight 
• friction 

The amount of matter in an object is 

• pressure
• weight
• mass
• force

Which of the following never changes no matter where in the universe?

• weight
• force
• mass
• pounds

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

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

Without gravity we would________. 

• Float away
• Stay in the ground
• Nothing would happen.
• I don't know
