  1. Forces, Machines and Work Jeopardy Final ?? TIE b. ??

  2. Forces for 10 What happens when an unbalanced force is applied to a sitting rock? A

  3. Answer to Forces for 10 • The rock moves in the direction of the force.

  4. Forces for 20 pts The force that pulls objects down is called ____.

  5. Answer to forces for 20 • GRAVITY or gravitational force Board

  6. Forces for 30 pts The effort it takes to pull a sled up an incline or lift a load is called the _______ _______. A

  7. Answer to forces 30 • Effort Force Board

  8. Forces 40 • Other than gravity, what two forces are acting on a paper airplane floating in the air?

  9. Answer to forces for 40 DOUBLE JEOPARDY • Fluid friction • Bouyant force • Balanced force Board

  10. What is defined as “The weight of the object being lifted”? A CHALLENGECHALLENGE CHALLENGE Forces for 50

  11. If you were challenged and were correct, you get 50 ptsIf you were challenged and was not correct, the team that challenged you gets 100 pts. • Load Force Answer to forces 50 Board

  12. 10 pts: Levers What is this type of lever called? A

  13. Answer to lever & Pulley 10 pt • First Class Lever Board

  14. Lever & pulley 20 Switcheroo • What is the name of this type of pulley

  15. Lever & Pulley answer to 20 pts.If correct, you must switch with another team. • Double fixed, single moveable PLUS you earn 40 pts more!! Board

  16. Levers & pulley for 30 A fixed pivot point of a lever is called the… A

  17. DOUBLE JEOPARDY!! • If Right You Earned 60 pts! Fulcrum Board board

  18. 40 pts. Levers What type of lever is the following? A

  19. 40 pts lever answer • Second class lever Board

  20. Levers for 50 pts Label the 4 parts you see in the following diagram: A

  21. Answer to 50 pt lever & pulley • Fulcrum • Load (or Resistance) force • Effort force • lever/arm/or rod Board

  22. Calculations for 10 pts: • How do I calculate for work? A

  23. Answer to calculations 10 • Work = Force in Newtons x distance in meters Board

  24. Calculations answer for 20! Free square = free points!! So stand at the right time….. board

  25. Calculations for 30 pts.: What units are Work measured in? Write it on the board…. A

  26. Calculations answer for : 30 pts! Work= Nm board

  27. How would I calculate for work output? Switcheroo !! From Calculations for40 pts. A

  28. Work Output = load force divided by effort force • If you got this right you may choose any table to switch the current table score with. • If you got this wrong you do not switch, but if a reasonable attempt made you may have 20 pts. Calculations answer for 40 pts. board

  29. Calculations for50pts: How would I calculate for Input work? Answer

  30. 50 pt. calculations DOUBLE JEOPARDY!! If right, you earned not 50 pts., but 100 pts! Work Input = Effort distance divided by load distance board

  31. Mixed bag for 10 What type of lever is the following: A

  32. Mixed Bag Answer for 10 • Third class lever Board

  33. Board Mixed bag for 20 pts Free Space! So stand at the right time….

  34. Mixed bag for 30 What does Inertia mean? A

  35. Mixed Bag Answer for 30 • In Newton’s First Law An object at rest will remain at rest, an object in motion will remain in constant motion, unless acted upon by an unbalanced force. Board

  36. Mixed bag for 40 • Read the following and tell me agent of force (Causing it), receiver of force, what happens and what the force is called: A 10-speed bike brake is pushed and the bike stops. Switcheroo PLUS DOUBLE!!

  37. Board Answer to m. bag 40 • If correct, switch with another and add 80 pts. • Not correct, means no switch and no double jeopardy! • agent of force (Causing it) : brake • receiver of force : tire (or 10-speed) • what happens : bike stops • what the force is called: friction

  38. Mixed bag for 50 • Explain how simple machines effect how work is done on an object

  39. Mixed Bag Answer for 50 DOUBLE JEOPARDY!! EARN 100 • A simple machine will reduce effort force needed and increase effort distance. (Work done on the object stays the same.) Board

  40. The following slides are final jeopardy

  41. FINAL JEOPARDYHOW MUCH ARE YOU RISKING??CLICK BELOW In order for your chair to hold you up it must ___.

  42. HOW MUCH DID YOU RISK?? Exert on you an equal force upward Board

  43. TIE BREAKER • What is the difference between mass and weight? DECIDE ON HOW MUCH TO WAGER AND WHOM TO ANSWER BY THEMSELVES: (YOUR WAGER ONLY AFFECTS THE TWO TIED) click below when ready -----

  44. Weight is the effect of gravitational force on an object’s mass while mass is only the matter and the space the object takes up. Board

  45. THE END •     
