Select the commonly used units of e. electron volts kcal/mole newtons meters m/s

Assuming the E you are referring to is Internal Energy, which refers to the total amount of the kinetic and potential energies of the particles that form your system. The common units for this internal energy are kcal/mole, and kJ/mol.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
