Equipotential refers to a concept in physics and engineering, particularly in the context of electric fields and gravitational fields. An equipotential surface is a three-dimensional surface on which every point has the same potential energy. ### Key Points about Equipotential Surfaces: 1. **Constant Potential**: On an equipotential surface, the potential difference between any two points is zero.
