This week we decided to further our knowledge in energy. We already knew some types of energy such as potential gravity, potential spring, kinetic, heat, and work. This week we learned a new type of energy that links what we learned about charges with what we already learned about energy. The new type of energy we learned is called electric potential energy. Electric potential energy or PEq is stored energy of a charged object in an electric potential field. PEq is measured in joules just like any other type of energy. In this picture I am holding a pack of AA batteries. We learned how to calculate voltage by dividing PEq by its charge. So AA batteries have a voltage of 1.5 volts. If a battery has a greater amount of voltage than it has a greater amount of electric potential energy.
