Today at the beggining of class, Finley asked us to get out our homework from monday and soon proceded to ask us what we thought Potential Energy was. After talking in our groups, Finley asked us what potential meant and the answer was when someone or something has the power to do something. We then went back to our chalk smashing ability experiment and said when I lifted the book I gave it potential energy. We then started on a summary and then proceeded to answer questions about postive work process. After we went on to share our answers. The type of energy we would get is Internal Energy because of friction. We concluded that if the surface that the crate was dragged on no friction being created so to creat energy we need the surface. A good link is
