  1. 1. The theoretical advantage of a machine without friction
  2. 4. The fixed pivot point of a lever
  3. 5. A larger wheel attached to a smaller axle that rotate together to reduce friction
  4. 6. A grooved wheel with a rope or cable that changes the direction of a force
  5. 8. A rigid bar that pivots on a fixed point (fulcrum) to lift or move a load
  6. 9. How much a machine multiplies an input force
  7. 11. A rotational force equal to force multiplied by lever arm distance
  8. 12. An inclined plane wrapped around a cylinder that converts rotational motion into linear force
