利用等效构造速度法,往往可以化难为易、化繁为简。在中学物理中,带电小球在复合场中的复杂曲线运动问题,应用等效构造速度法去研究,可以使原本无法解决的物理问题思路豁然,分析和解答变得简捷。笔者命制了两例带电小球在复合场中的曲线运动问题,应用等效构造速度法来解决,以供同仁共同探讨。一、等效实构速度法例1如图1所示,在竖直平面xOy中的第三、
The use of equivalent structure speed method, often can be difficult for the easy, simplistic. In middle school physics, the problem of complex curve movement of charged pellets in a compound field and the application of the equivalent structure velocity method can make the original unresolved problems of physical problems suddenly become obvious, and the analysis and solution become simple. I ordered two cases of charged balls in the composite field curve motion problems, the application of equivalent structure speed method to solve, for my colleagues to discuss. First, the equivalent real speed law 1 shown in Figure 1, in the vertical plane xOy in the third,
