The force of gravity on a person or object on the surface of a planet is called

• mass.

• terminal velocity.

• weight.

• free fall.

You weight 200 lbs on Planet A and 150 lbs on Planet B. Which planet has a larger gravitational pull?

• Planet A

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
