电势能是静电学部分的重要概念,也是教学的难点,为了使学生准确地掌握电势能的物理意义,需要将电势能的计算问题进行梳理。通过对电势能的理论分析,明确电势能与静电力功的关系对理解静电场的内容有很大的帮助。 Potential energy is an important part of the electrostatic concept, but also teaching difficulties, in order to enable students to accurately grasp the physical meaning of potential energy, the calculation of potential energy needs to be combed. Through the theoretical analysis of the potential energy, a clear understanding of the relationship between potential energy and electrostatic power contributes to the understanding of the contents of the electrostatic field.
