应用整体法,常有两种情况: 1.多个物体组成整体 当讨论两个或两个以上物体和外界的相互作用,而不研究物体间的相互作用时,可将这些物体看作一个整体. 2.多个过程组成整体 由多个过程组成的问题,若不需研究过程的细节,只要明确过程的初末状态,可将多过程看作一个整体来处理. 例1 在场强为E的匀强电场中固定放置两个小球1和2,它们的质量相等,电量分別为
There are two common situations when applying the holistic approach: 1. When multiple objects form a whole When discussing the interaction between two or more objects and the outside world without studying the interaction between objects, these objects can be considered as a whole. 2. The multiple processes make up the whole problem of multiple processes. If you do not need to study the details of the process, as long as the initial state of the process is clear, the multiple processes can be treated as a whole. Example 1 The field strength is E. In the uniform electric field, two small balls 1 and 2 are fixedly placed. Their masses are equal, and the electric quantity is respectively
