WebYes, since the choice of the zero of potential energy is arbitrary. Is negative potential possible? Answers and Replies. Electric potential can be negative if you go close enough to a negative charge. One important point, however: the potential does not have an absolutely defined value, you have to arbitrarily give it a value at a certain point. WebThe sum of kinetic energy and potential energy of a bound system has a value less than zero. But the total energy which includes the masses individually gains a positive value. An isolated system should have a positive value of its total energy. ... Conservation of energy can not have a negative value as it is totally violating the law of ...

WebPotential energy increases when the charges move opposite the direction of the electric force, for example, when two negative charges get closer together. Similarly, magnetic potential energy is the potential energy a magnetic object has due to the magnetic force from another magnet. Magnetic force causes similar poles to repel one another, and ... WebMay 23, 2012 · Potential energy can be negative, and often is. Any attractive force has a negative potential energy. If you take an electron and positron together, the total energy shrinks as you move them closer together, because the coulomb potential becomes more negative. A bound system will have the sum of potential energy and kinetic energy …
