Why does the gravitational force between earth and moon predominate over electrical forces? the electric force between earth and moon cancels out because they have an equal number of positive and negative charges. the gravitational force between two protons is billions of times stronger than the electrical force. gravitational forces grow exponentially with the number of particles, while electrical forces simply add. the electrical force gets smaller more quickly with distance than the inverse square gravitational force
