(i.e.) there is no direct conversion of P.E. in the rod to the K.E. of the line as the rod unloads. The force from the rod enters into the work energy calculation, but the distance that force is applied is much further than the just the deflection distance of the rod because the caster is moving the rod tip over a larger distance.
