  1. 2. the ability to cause change; measured in Joules (J)
  2. 5. Law of _______________________ states that energy cannot be created or destroyed
  3. 7. ratio of the output force exerted by a machine to the input force applied to the machine
  4. 8. transfer of energy when a force is applied over a distance; measured in Joules (J)
  5. 9. energy a moving object has because of its motion; determined by the mass and speed of the object
  6. 11. machine that does work with only one movement; examples include lever, pulley, wheel and axle, inclined plane, screw, and wedge
  7. 13. energy that is stored by compressing or stretching an object
  8. 14. energy that is stored to the interactions between objects
  9. 15. energy that is due to chemical bonds
  10. 16. ratio of the output work done by the machine to the input work done on the machine, expressed as a percentage

  1. 1. machine that is a combination of two or more simple machines
  2. 3. energy that is due to the gravitational force between objects; also GPE
  3. 4. rate at which energy is converted; measured in Watts (W)
  4. 6. region or set of regions around which a boundary can be defined
  5. 10. device that makes doing work easier by increasing the force applied to an object, changing the direction of an applied force, or increasing the distance over which a force can be applied
  6. 12. energy that is the sum of the potential energy and kinetic energy of the objects in a system
