WebWork done on a body is equal to the increase in the energy of the body, for work transfers energy to the body. If, however, the applied force is opposite to the motion of the object, the work is considered to be negative, implying that energy is taken from the object. The units in which work is expressed are the same as those for energy, for example, in SI … WebW W is the net work done on the system. So positive heat Q Q adds energy to the system and positive work W W adds energy to the system. This is why the first law takes the form it does, \Delta U=Q+W ΔU = …
