  1. 4. Work Formula
  2. 5. a simple machine made of a rigid beam and a fulcrum.
  3. 7. When a force causes something to move a distance
  4. 9. a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim.
  5. 11. mechanical devices that are used to make work easier
  6. 12. measures the length between objects or points without regard for direction.
  7. 13. How much easier the machine makes the work

  1. 1. the mechanical advantage determined by physical measurement of the input and output forces
  2. 2. a small metal rod with a notch in the top that's used as a fastener.
  3. 3. is the mechanical advantage of a perfect machine with no loss of useful work caused by friction between moving parts.
  4. 4. a type of simple machine used to make tasks easier in terms of manipulating force by applying the concept of mechanical advantage. The wheel and axle consists of a round disk, known as a wheel, with a rod through the center of it, known as the axle.
  5. 6. The standard unit used to measure energy and work done in physics is the
  6. 8. a measure of the opposition to current flow in an electrical circuit.
  7. 10. simple machine consisting of a sloping surface, used for raising heavy bodies
