  1. 2. a type of lever that is a wheel with a groove in its rim and one that is used to change the direction of a force
  2. 4. The S1 unit of power one watt is expended when one joule of work is done in one second
  3. 6. a simple machine made of a bar that turns about a fixed point
  4. 9. energy energy of position usually related to the relative position of two things such as a stone and the earth
  5. 11. The product of the force on an object and the distance through which the object is moved
  6. 12. the ratio of useful energy output to total energy input or the percentage of the work input that is converted to work output
  7. 14. energy energy of motion equal to half the mass multiplied by the speed squared
  8. 15. of conversation of energy energy cannot be created or destroyed it may be transformed from one form into another but the total amount of energy never changes

  1. 1. the S1 unit of work and of all other forms of energy one joule of work is done when a force of one newton is exerted on an object moved one meter in the direction of the force
  2. 3. Rate at which work is done or energy is transformed equal to the work done or energy transformed divided by time
  3. 5. a device for increasing or decreasing a force or simply changing the direction of a force
  4. 7. that property of an object or system which enables it to do work
  5. 8. energy the energy due to the position or the movement of something potential or kinetic energy
  6. 10. advantage the ratio of output force to input force for a machine
  7. 13. the pivot point of a lever
