2. Work
Work is done when a force causes an object to move over a distance.
The amount of work depends on the amount of force and the distance the object is moved.

3. Calculating Work Work = Force x Distance W = F · D
If the object does not move a distance, than no work has been done.
Units are N· m or Joules
