Potential Energy, Conservative Forces, and Cons. of ME
... Before we define the potential energy function mathematically, we need to define a conservative force. Conservative Forces Conservative forces are very important because as we will see they imply conservation of energy for an isolated system. With every conservative force there is a potential energy ...
