I have told you this many times already. Energy has been expended, but no work has been done. What is not helpful for the debate is for you to use the incorrect terminology when the correct terminology has been provided. These are technical words with specific mathematical meanings. If you want to learn science, which you have claimed several times is your goal, then you need to learn the meanings of the terms and use them correctly.waynexk8 said:I do not think the meaning of work, that is if you move a weight up and then down = zero, is helping this debate at all. As we all know here that force and energy have been used to lift the weight and to lower it under control, thus physical work has been done.
