Question

directions: for each description below, explain how the mass and weight of each person are affected. write up, down, or same.
remember: mass changes when matter is added or taken away.
weight changes when matter is added or taken away.
weight changes when the gravitational pull increases or decreases.
descriptions

1. you travel from earth to the moon with nasas next mission.
2. you are skiing in new hampshire. its cold, so you put on several sweaters.
3. nasa geologist jessica watkins travels to mars to study olympus mons, the largest volcano in our solar system. (well, she hasnt yet... but soon!) mars has 10 times less mass than earth.
4. your friend will moved from hawkins, indiana to a town in maine.
5. you got your back - to - school haircut. you look amazing!
6. astronaut mae jemison flies in the space shuttle and docks at the international space station in space.
7. you study really hard for your science quiz and get a 100.
8. you give your dog a kiss on the head and he wags his tail.
9. you eat ten slices of pizza on a dare from a friend.
10. ten slices of pizza then exit your body. we dont need details.
11. your cat, steve, plays minecraft (a video game) in your living room when you arent home.
12. a ninja plays the video game fortnite on the moon.
13. safiya puts lots and lots of makeup on her face.
14. your music teacher, mr. drake, puts on a funky hat.
15. you accept a “free offer” to stand on the surface of jupiter (though you are suspicious because you know jupiter doesnt have a solid surface). because jupiter has so much matter, its gravitational pull is over twice that of earths.
16. you sign up to be one of the first people on mercury. you set off on the spaceship and land on mercury (mercury has a smaller mass than earth.) you are instantly homesick and regret your decision.

Explanation:

Step1: Recall mass and weight concepts

Mass is amount of matter, weight is gravitational - force on mass.

Step2: Analyze travel to moon

Mass is same as no matter added/removed, weight goes down as moon's gravity is less.

Step3: Analyze skiing with sweaters

Mass goes up as adding matter (sweaters), weight goes up as more mass in same gravitational field.

Step4: Analyze travel to Mars

Mass is same as no matter added/removed, weight goes down as Mars has less mass than Earth (less gravity).

Step5: Analyze moving within Earth

Mass and weight are same as gravitational field and amount of matter unchanged.

Step6: Analyze haircut

Mass goes down as matter (hair) is removed, weight goes down as mass decreases.

Step7: Studying hard has no effect

Mass and weight are same as no change in matter or gravitational field.

Step8: Kissing dog has no effect

Mass and weight are same as no change in matter or gravitational field.

Step9: Eating pizza

Mass goes up as adding matter (pizza), weight goes up as more mass in same gravitational field.

Step10: Pizza exiting body

Mass goes down as matter is removed, weight goes down as mass decreases.

Step11: Cat playing video - game has no effect

Mass and weight are same as no change in matter or gravitational field.

Step12: Ninja on moon

Mass is same as no matter added/removed, weight goes down as moon's gravity is less.

Step13: Putting on makeup

Mass goes up as adding matter (makeup), weight goes up as more mass in same gravitational field.

Step14: Wearing a hat

Mass goes up as adding matter (hat), weight goes up as more mass in same gravitational field.

Step15: Standing on Jupiter

Mass is same as no matter added/removed, weight goes up as Jupiter has stronger gravitational pull.

Step16: Traveling to Mercury

Mass is same as no matter added/removed, weight goes down as Mercury has less mass than Earth (less gravity).
