电场具有力的性质和能的性质,电荷在电场中受到电场力的作用,具有电势能．所以很多静电问题与力学知识紧密联系．解答这类静电综合题应注意将力学中的研究方法迁移运用,从受力分析、运动状态分析入手,应用静力学知识、牛顿运动定律和运动学公式;从动量、能量的观点入手,应用动量守恒定律和能量守恒定律,结合相关电场的知识,进行分析求解．
The electric field has the nature of the force and the nature of the energy. The electric charge is affected by the electric field force in the electric field and has electric potential energy. Therefore, many electrostatic problems are closely related to the knowledge of mechanics. To solve this kind of electrostatic comprehensive problem, we should pay attention to the migration of research methods in mechanics, starting from stress analysis and motion state analysis, applying static knowledge, Newton’s laws of motion and kinematics formulas; starting with momentum and energy, applying momentum The law of conservation and the law of conservation of energy, combined with the knowledge of the relevant electric field, are analyzed and solved.
