Work is a form of energy.
A Watt is the standard metric unit of work.
Work is a time-based quantity; it is dependent upon how fast a force displaces an object.
None of the above.
Moving objects cannot have potential energy.
Both gravitational and elastic potential energy are dependent upon the mass of an object.
Potential energy is the energy stored in an object due to its position.
None of the above.
