Which one of the following is not a form of stored energy ?

Energy is broadly categorized into potential (stored) and kinetic (motion) energy [2]. Potential energy is the energy of position or state [2]. Chemical energy is stored in the bonds of atoms and molecules, such as in batteries or fuels [4]. Nuclear energy is stored within the nucleus of an atom, holding it together [2]. While electrical energy can be stored in specific components like capacitors or as potential energy in an electric field, it is primarily characterized by the movement of charged particles (electrons) through a conductor to perform work [3]. In standard physics classifications, electrical energy is often treated as a form of kinetic energy (the flow of electrons) or a medium of energy transfer rather than a primary 'stored' form like chemical, nuclear, or gravitational potential energy [3]. Therefore, electrical energy is the least representative of a 'stored' form among the options.
