An average bowling ball has a mass of 7.26 kilograms. On Earth, it would weigh 16 pounds. On the moon, where the force of gravity is much weaker, the ball’s mass would still be 7.26 kilograms. However, because gravity isn’t pulling it down as strongly, it would weigh only 2.65 pounds. Which of the options listed below would be true if you stood on the moon?

• your mass would increase

• you would weigh more than you do on Earth

• you would weigh the same as you do on Earth

• Your same mass would stay the same

Mass and weight are different. Mass depends on _____. Weight depends on _____.

• gravitational force, the amount of matter

• placement, force

• force, placement

• the amount of matter, gravitational force

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

• weight

• force

• mass

• pounds

If an object mass =30 Kg on the Earth, what would be it's weight on Earth?

• 30 N

• 300 kg

• 3000N

• 300 N
