What are you asking? The use of something with potential energy can convert that to kinetic and then to another form of energy such as heat. This energy can be used to drive a multitude of things. One of the prime examples is a hydroelectric dam. It uses the potential energy of water changing into kinetic energy as it flows downhill and converts that into electrical energy. You will have more than enough energy to overcome friction, as the rest is converted into electrical energy. However, some of that energy WILL be lost as friction and other effects that there is no way to overcome unless you could get rid of the friction.wow I am glad I joined this site however from the completely dumb level I come from I can almost see how this argument can be solved "proof" all the big names I have spoken to about this all say it cant be done because of this and that and the other thing but none of them talk about the use of potential energy and how it can be used in a way to over come the energy loss through friction can some one help me out with this one please???
