  1. 2. The resistance that one surface or object encounters when moving over another.
  2. 6. The ratio of the force that performs the useful work of a machine to the force that is applied to the machine. MA = F0 / Fi
  3. 7. A piece of a substance (as wood or iron) that tapers to a thin edge and is used for splitting wood and rocks, raising heavy bodies, or for tightening by being driven into something.
  4. 8. An assembly of moving parts completing a complete functional motion.
  5. 10. A full-scale working model used to test a design concept by making actual observations and necessary adjustments.
  6. 12. A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original.
  7. 14. A flat surface set at an angle used to help raise or lower objects.
  8. 15. A twisting force.
  9. 16. The ability to do work.

  6. 10. A solid disc that rotates around a center axis. It usually has a groove around the outside edge that allows ropes or belts to easily ride around it.
  7. 11. The unit of energy or work in the MKS system of units, equal to the work done by a force of one Newton-meter.
  8. 13. The energy which a body possesses because of its motion.
  9. 17. A cylinder with a spiral ridge or thread running round the outside that can be turned to seal an opening, apply pressure, adjust position, etc.
  10. 18. The point around which a lever turns or is supported.
