物理中的一些常见的比较类问题,倘若采用通式法去解将会大大简化解题过程,减少运算量,提高解题效率,有事半功倍的效果.一、可利用通式法解决的问题的特征看两个例子:例1有三个光滑斜轨道1、2、3,它们的倾角依次是60°,45,°30°,这些轨道交于O点.现有位于同一竖直线上的3个小物体甲、乙、丙,分别沿这3个轨道同时从静止自由下滑,如图1所示,物体 Some common physical comparison problems, if the general solution to the solution will greatly simplify the problem-solving process, reduce the amount of computation and improve the efficiency of problem-solving, with multiplier effect. First, the problem can be solved using the general method Features Two examples are shown: Example 1 There are three smooth inclined orbits 1, 2, and 3 whose angles of inclination are 60 °, 45 ° and 30 °, respectively, and these orbits are at point O. Existing 3 A small object A, B, C, respectively, along the three tracks simultaneously from the static free fall, as shown in Figure 1, the object
