D) Power has a time component while energy does not.

The difference between energy and power lies in the time aspect:

  • Energy is the ability to do work and is measured in joules. It is a scalar quantity.
  • Power is the rate at which energy is transferred or the rate at which work is done. Power is measured in watts (joules per second) and has a time component, representing the amount of energy transferred or work done per unit of time.
