  1. 4. A simple machine with a rigid arm that turns around a fulcrum with an input and output force.
  2. 5. A simple machine that consists of a rope that fits into a groove in a wheel that you may use to lift things.
  3. 9. A number that tells us how many times a machine multiplies force; it can be calculated by dividing the output force by the input force.
  4. 12. A class of lever in which the fulcrum is somewhere between the applied force and the load.
  5. 14. A simple machine that is 2 inclined planes placed back to back; when moved it turns a single downward force into 2 forces directed outward at the side.
  6. 15. A unit which measures how much work has been accomplished; Newton x meters.
Down
  1. 1. A simple machine that consists of two attached circular or cylindrical objects that rotate about a common axis, each one with a different radius.
  2. 2. A quantity that measures the rate at which work is done or energy is transformed.
  3. 3. A device, of which there are 6 different types, which make work easier by reducing the amount of force necessary to complete the work.
  4. 6. A machine made up of more than one simple machine.
  5. 7. A class of lever in which the fulcrum is at one end, the load is in the middle, and the applied force is at the other end.
  6. 8. A unit which measures the amount of power that has been produced; J/s.
  7. 10. A class of lever in which the fulcrum is at one end, the applied force is in the middle, and the load is at the other end.
  8. 11. A simple machine that is an inclined plane wrapped around a central cylinder to form a spiral; when more vertical, more force is required over less distance.
  9. 13. A result of a force moving an object a certain distance.
