1. Gravity Quiz

2. Q1: Which of these would have more gravity?
A: Jupiter! (More mass = more gravity)
Jupiter
Earth

3. Q 2: The result of gravity pulling on us is called:
A: Weight More mass = more weight

4. Q 3: Why can’t the astronaut move the space station?
Roger Houston! Here I go!
(use the two skateboards & push)
A: It has too much inertia (more mass = more inertia)

5. Q 4: What doesn’t change when you visit the moon:
A: Your mass (Weight changes, mass does not)

6. A: They both hit at the same time
Q 5: When Galileo dropped the different size cannonballs from the tower, which hit the ground first?
Hmmm?
A: They both hit at the same time

7. Q 6: True/False: A larger object will always weigh more than a smaller object:
A: False!

8. Q 7: Why do all the planets orbit around the Sun?
A: The Sun has the most Mass! (more mass=more gravity)

9. Q 8: Why do feathers fall slower than rocks in “normal conditions”?
A: Air friction slows it down

10. A: Earth is closer! More distance = less pull of gravity
Q 9: If the sun has so much more mass & gravity than the earth, why don’t we get pulled all the way to the sun?
A: Earth is closer! More distance = less pull of gravity

11. Q 10: The proper unit for weight is:
A: Newton!

12. Q 11: What is Mass?
A: The amount of matter (atoms, molecules, “stuff”) that makes an object up

13. Q 12: What would the mass of a 78 kg person be in space?
A: 78 Kg (Mass does not change)
