3. Rules (1) White numbers indicate that Answer has already been selected. (2) You must answer in the form “What is…” (3) While it is another teams turn, you may record the answer to the question on your white board. If the other team fails to answer the question, all other teams with the correct answer on their white board will earn 50 points. (4) You may not talk during another teams turn. If you talk you will not be eligible for extra points. (5) During Final Jeopardy you may not risk more points than you have. ©Norman Herr, 2003

4. Question Answer A-100 ANSWER: This exerts the force of gravity. QUESTION: What is everything?

5. Question Answer A-200 ANSWER: Objects accelerate towards the earth at this rate. QUESTION: What is 9.8 m/s/s?

6. Question Answer A-300 ANSWER: This happens to the pull of gravity when the distance between two objects increases. QUESTION: What is the gravity decreases?

7. Question Answer A-400 ANSWER: These two things combine to create orbit. QUESTION: What is velocity of the object in orbit and the pull of gravity of the planet?

8. Question Answer A-500 ANSWER: This is the Law of Universal Gravitation. QUESTION: What is the gravity between two objects increases as mass increases and decreases as distance increases?

9. Question Answer ANSWER: This is what friction does to objects. QUESTION: What is slow objects? B-100

10. Question Answer B-200 ANSWER: Friction produces this QUESTION: What is heat?

11. Question Answer B-300 ANSWER: Make a surface smoother will do this to friction. QUESTION: What is decrease it?

12. Question Answer B-400 ANSWER: These are two ways to increase the friction on an object. QUESTION: What is rough up the surface or increase the weight?

13. Question Answer B-500 ANSWER: When surface area is increased, this becomes greater. QUESTION: What is the forces of air resistance?

14. Question Answer C-100 ANSWER: Pressure depends on these two things QUESTION: What is force and area?

15. Question Answer C-200 ANSWER: This is the pressure a 10N object with a surface area of 2 m 2 would apply to a table. QUESTION: What is 5 Pascals?

16. Question Answer C-300 ANSWER: This is why pressure increases as you dive deeper into the ocean. QUESTION: What is there is more water on top of you?

17. Question Answer C-400 ANSWER: As this increases the air density and pressure decreases. QUESTION: What is altitude or elevation?

18. Question Answer C-500 ANSWER: These are two things you could do to this box to decrease the pressure. QUESTION: What is lie it on its side and make it lighter?

19. Question Answer D-100 ANSWER: This is the upward push in water. QUESTION: What is buoyant force?

20. Question Answer D-200 ANSWER: This is how an object’s ability to float relates to density. QUESTION: What is if an object is less dense than the fluid it is in, it floats?

21. Question Answer D-300 ANSWER: He discovered the relationship between the weight of the displaced water and an object’s ability to float. QUESTION: Who is Archimedes?

22. Question Answer D-400 ANSWER: This is why buoyant force exists. QUESTION: What is the pressure is greater at the bottom of a body of fluid, creating and upward push?

23. Question Answer D-500 ANSWER: An 30g object floats if it displaces this much weight of fluid. QUESTION: What is 30g or more?

24. Question Answer E-100 ANSWER: Of mass and weight, this one changes on a different planet. QUESTION: What is weight?

25. Question Answer E-200 ANSWER: This is the kind of pressure exerted by a moving stream of fluid. QUESTION: What is low pressure?

26. Question Answer E-300 ANSWER: The weight of the displaced water is equal to this. QUESTION: What is the strength of the buoyant force?

27. Question Answer E-400 ANSWER: This is why air resistance is affected by surface area. QUESTION: What is a object with a greater surface area will be pushed up by (or catch) more particles than an object with little surface area?

28. Question Answer E-500 ANSWER: This is an explanation of how Bernoulli’s Principle helps smoke rise from a chimney. QUESTION: What is the moving air creates an area of low pressure above the chimney. In contrast, the air in the chimney is at high pressure. The high pressure air move towards the low pressure air, helping the smoke rise.

29. Question Answer FINAL JEOPARDY ANSWER: The moon has no atmosphere. Could you safely skydive on the moon? Explain. QUESTION: No. Without an atmosphere, there is no air resistance and so you could not slow down with the use of a parachute.
