WebThe gain of potential energy as it moves from A to B to C is consistent with the fact that the satellite moves further from the surface of the earth. As the satellite moves from C to D to E and back to A, it gains speed and loses height; subsequently there is a gain of kinetic energy and a loss of potential energy. WebEarth's potential is close to zero which remains unaffected by addition of charges. So, there's always a potential difference maintained with source even when direction of AC changes. Half of times, source is at higher potential than Earth and half of times, it's at lower potential. But, it's never at equal potential to Earth. in your hands lord i surrender all lyrics
