Answer :
Work and energy are the same thing. Their unit is the Joule.
One joule means the energy it takes to push with a force of 1 newton
through a distance of 1 meter.
The unit of power is the Watt. That's the rate of work or energy.
One watt means using 1 joule of energy (for example, push with a force of
1 newton through a distance of 1 meter), and doing that in exactly 1 second.
