_____________________________________

14. Why does all matter experience gravity?

A. All matter has volume.

B. All matter has mass.

C. All matter is constant.

D. All matter is stable.

Hamster, elephant, skyscraper, the moon

The puppy’s mass is not constantb/c matter is being added to the puppy as it grows.

15. As two objects get _____________, the force of gravity between them increases.

16. Weight is a measure of the gravitational force exerted on an object. True… False…

17. A brick weighs less in space than on earth. Why? _______________________________

_____________________________________18. Why do people confuse the terms weight

and mass? A. They appear constant on earthB. People use the words interchangeably.C. Mass is the same as weight. D. Mass is also dependant on gravity.

closer together

b/c the gravitational pull is less in space

than on the surface of the earth.

19. The unit for ________ is the Kilogram.

The unit for __________ is the Newton.

20. How do mass and inertia make it easier to pick up an empty juice bottle than a full one? _____________________________

See review on p. 42

mass

weight

Full bottle has more mass than the

empty one. More mass = more inertia. Full

one is harder to put into and out of motion.
