Work is force applied over distance. Is it also reasonable to say that work is (the same thing as) the transfer of energy?
When work is done, the equivalent energy is transferred. But if energy is transferred, such as by heating something, is that (or could that be) called work?
Also, if a black body is subjected to a stream of energy, which it absorbs and radiates away, is any work done? The black body, let's assume, remains at a constant temperature, but energy is transferred to it and then radiated away. Is any work done?
So what I'm really asking about is how the term "work" should be used.
