  2. JEOPARDY

  3. Question States of Matter (100) • What is a Force?

  4. ANSWERStates of Matter (100) • A push or a pull

  5. Question States of Matter(200) • What two ways is a force described?

  6. Answer States of Matter (200) • By the direction it acts and its strength.

  7. Question States of Matter(300) • In a force diagram, one arrow is longer than the other. What does that tell us about the two forces?

  8. Answer States of Matter(300) • The longer arrow is a stronger force.

  9. Question States of Matter(400) • If force arrows are pointing in opposite directions, how would you determine the net force?

  10. Answer States of Matter(400) • Combine them by subtraction.

  11. Question States of Matter(500) • If you exert a force of 170N on a desk and your friend exerts a force of 230N in the same direction what is the net force?

  12. Answer States of Matter(500) • 400N

  13. Question Changes of State (100) • What are the 4 types of friction?

  14. Answer Changes of State (100) • Static • Sliding • Rolling • Fluid

  15. Question Changes of State (200) • What factors affect the friction force between two surfaces?

  16. Answer Changes of State (200) • Nature of the two surfaces • How hard they push together

  17. Question Changes of State (300) • What is the Law of Universal Gravitation?

  18. Answer Changes of State (300) • The force of gravity acts between all objects of the universe

  19. Question Changes of State (400) • Why does an object accelerate as it falls towards the Earth’s surface?

  20. Answer Changes of State (400) • Gravity

  21. Question Changes of State (500) What force changes when a sky diver’s parachute opens? What force stays the same?

  22. Answer Changes of State (500) • Air resistance changes • Gravity stays the same

  23. Question Gas Behavior (100) • What does Newton’s first law of motion state?

  24. Answer Gas Behavior (100) • An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by another force.

  25. Question Gas Behavior (200) • What is Newton’s Second Law of Motion?

  26. Answer Gas Behavior (200) • Acceleration depends in the object’s mass and the net force acting on the object.

  27. Question Gas Behavior (300) • What are two ways to increase the acceleration of an object?

  28. Answer Gas Behavior (300) • Decrease mass • Increase force

  29. Question Gas Behavior (400) • If the net force on a soccer ball is 40N and it has a mass of 5kg what is its acceleration?

  30. Answer Gas Behavior (400) • 8 m/s2

  31. Question Gas Behavior (500) • Why is Newton’s First Law of Motion also called the Law of Inertia?

  32. Answer Gas Behavior (500) • Inertia is an object’s tendency to resist motion and that is the same idea as Newton’s First Law.

  33. Question Graphing Gas Behavior (100) • What is Newton’s Third Law of Motion?

  34. Answer Graphing Gas Behavior (100) • One object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction.

  35. Question Graphing Gas Behavior (200) • How are action and reaction forces related?

  36. Answer Graphing Gas Behavior (200) • Equal in strength but in opposite directions.

  37. Question Graphing Gas Behavior (300) • What is momentum?

  38. Answer Graphing Gas Behavior (300) • Characteristic of a moving object equal to the product of its mass and its velocity.

  39. Question Graphing Gas Behavior (400) • What is conservation of momentum?

  40. Answer Graphing Gas Behavior (400) • Without an outside force like friction, the quantity of momentum is the same before and after the objects interact.

  41. Question Graphing Gas Behavior (500) • If the total momentum of two trains before a collision is 15kg x m/s, what is the total momentum after the collision (assuming there is no friction)?

  42. Answer Graphing Gas Behavior (500) • 15kg x m/s • It stays the same

  43. Question Vocabulary (100) • What is a satellite?

  44. Answer Vocabulary (100) • Any object that orbits another object in space.

  45. Question Vocabulary (200) • How do rockets lift off?

  46. AnswerVocabulary (200) • The rocket puts out a gas that has a downward force and then an equal but opposite force pushes on the rocket to make it go up.

  47. Question Vocabulary (300) • What is the force called that causes an object to move in a circular motion?

  48. AnswerVocabulary (300) • Centripetal force

  49. Question Vocabulary (400) • What causes satellites to stay in orbit rather than fall towards the Earth?

  50. AnswerVocabulary (400) • Since Earth is curved, the satellites fall towards the Earth but instead travel around it.
