I have just started taking a beginner physics course and am currently studying work and its basic components [ie. W=F(d)]. now i understand the concept, but i am curious about the idea that just because something doesnt move or change its condition as a whole that the amount of work is zero. for example: a man pushing on the side of his house with all his strength he can muster. Now of course we all know the man wont be able to move the house, but to say no work has been done cant be right. i am talking on a very minimal level. like the changing of some of the matter of the brick or siding that he had his hands on. just because the entire object is not effected does that mean a small part that might be affected is simply overlooked in the entire scheme of things?
