Expression like a ton of bricks means “a crushing weight.” Would being hit a ton of bricks hurt if it was on the moon? (5.13)

• No, it would not hurt because the bricks would have little mass.

• Yes, it would hurt because the bricks would still have the same mass.

• No, it would not hurt because the bricks would have more weight.

• Yes, it would hurt because the bricks would still have more weight.

What happens to the density of a material if you have a larger piece of it? (5.13)

• density will remain the same because mass and volume will remain the same.

• density will be small due to mass remains the same as the volume increases.

• density will remain the same due to mass and volume both increasing at the same time

• density will be big due to the mass increases but volume remains the same.
