An astronaut having a mass of 65kg is standing on the surface if the koon. the mass if the moon is 7.36 x 10^22kg and the radius is 1.74 x 10^6m what is the gravitational force the astronaut exerts on the moon

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
