I am still confused about this.
say, we are in a constant moving truck, we pushed the back of the truck, so we provide the force F on the walls of the truck, towards the rear. but the truck moving with constant velocity and has traveled a distance of say x. we do the work according to an inertial frame (the earth) is =-Fx, but what if we use our truck frame, according to the truck, we do not do work, but why do we become tired if you continue doing that work, where energy is lost?
