Explanation:

Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement.

Power is the rate at which that work is done.

work = f.d = n.m = j  =  \frac{ {kgm}^{2}}{ {s}^{2} }  \\  \\ power = f. \frac{d}{t}  = f.v =  \frac{n.m}{s}  = w =  \frac{j}{s}  \\  =  \frac{ {kgm}^{2} }{ {s}^{3} }

As an example, a racing car and a family sedan might have the same mass. To get both moving at a speed of 30 m/s requires the same amount of work. However, since the racing car has more power, it can reach that speed in a shorter amount of time,
