Power: The amount of work performed per unit time.
For example, if I accelerate an object of mass M from rest with constant force and for t seconds then the distance the object traveled can be calculated using force/mass=acceleration and then plugging the found acceleration into d=1/2at^2. So now I know Force and Distance and can find the work done. Also I know the time it took to do the work (which was t) and thus can calculate power. So power and work are really the same thing in disguise.
