Across
  1. 3. a comparison of a machine's work output with the work input
  2. 5. energy that an object has because of the position, shape, or condition of the object
  3. 6. work done on a machine;product of the input force and the distance through which the force is exerted
  4. 7. the rate at which energy is transferred
  5. 8. the amount of work an object can do because of the object's kinetic and potential energy
  6. 11. a simple machine that is a straight, slanted surface
  7. 14. unit used to express energy
  8. 17. energy of an object that is due to the object's motion
Down
  1. 1. an inclined plane that is wrapped in a spiral around a cylinder
  2. 2. a device that makes work easier by changing the size or direction of the force
