Simple Machines: Topic 1-3 Review - Call List

(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

  1. Heat and friction within the engine
  2. 50J
  3. 2.4kJ
  4. MA increases
  5. 4
  6. 4m
  7. 214N
  8. Second Class
  9. You travel a longer distance to lift the load the same height; input distance increases with a shallow ramp
  10. 6
  11. To decrease friction and increase efficiency
  12. MA = circumference/pitch
  13. 300N
  14. 9
  15. Less than 1
  16. MA increases
  17. 2
  18. 425N
  19. Friction decreases efficiency; SR represents ideal MA
  20. 8
  21. Heat and sound
  22. MA decreases
