Explanation:
<u><em>Work done</em></u> is is the energy transferred to or from an object by means
of a force acting on the object.
Work is positive if energy transferred to the object, and work is
negative if energy transferred from the object.
<em>Work = Force in the direction motion of object × its displacement</em>

The SI unit of the work is joule (J)
<u><em>Power</em></u> is the rate of work
<em>Power = work done ÷ time taken</em>
Power = 
Displacement (s) ÷ time (t) = velocity (v)
<em>Power = Force × velocity</em>

The SI unit of the power is watt (w)
