Across
  1. 3. This insect uses a lever action in it's legs when it jumps.
  2. 5. The horizontal distance that a ramp covers.
  3. 6. A tiny inclined plane wrapped around a cylinder.
  4. 8. Simple machines do not reduce the amount of _____ being done.
  5. 9. A beam or bar that pivots on a fixed point.
  6. 13. An object that resists the force applied by simple machines.
  7. 14. Another name for the fulcrum.
  8. 16. A device that makes work easier and which has few or no moving parts.
  9. 17. The maximum height of a ramp.
  10. 18. The force that is applied to a simple machine.
  11. 21. A straight, slanted surface used to raise an object.
  12. 22. In this type of lever, the load is between the fulcrum and effort. Ex: Wheelbarrow (hyphen in answer)
Down
  1. 1. When a simple machine is used to do work, often the work requires less ______ over a greater distance.
  2. 2. A lever that has a wheel and rope attached to it that allows the user to change the direction of the force.
  3. 3. A measure of the steepness of a slope.
  4. 4. The point where a lever rotates or pivots.
  5. 7. This is a combination of 2 inclined planes.
  6. 8. This simple machine is used to draw a bucket of water up in a water well.
  7. 10. These inclined planes reduce the amount of force needed to move an object.
  8. 11. One of the earliest tools found.
  9. 12. The handle of this tool is considered a lever.
  10. 15. This type of lever has the fulcrum directly between the effort and the load. Ex: Seesaw (hyphen in answer)
  11. 17. In this lever, the effort is between the load and the fulcrum. Ex. Tweezers (hyphen in answer)
  12. 19. Simple machines can change the amount of ____ applied to an object.
  13. 20. Simple machines can alter the ______ of the force applied to an object.
  14. 22. When a longer ramp is used to decrease the amount of effort, the steepness of the _____ also decreases.
