辩证唯物主义认为:一般与特殊是辩证的统一体.任何特殊都包含着一般,一般存在于每一特殊之中.一般与特殊的这种辩证关系启示我们,解题应当善于对问题进行从一般到特殊和从特殊到一般的转化.下面结合实例谈谈特殊与一般转化这一重要思维方法在物理解题中的应用.一、由一般演绎出特殊许多物理问题的文字解具有一般性的意义,对其进行演绎讨论导出典型特例下的结论,可以使我们对事物认识得更具体,从而使思维从抽象上升到具体.而且,因为典型特例往往很常见,所以,演绎得到的结论具有很大的实用性.记住这些结论,可以对某些物理问题迅速作出判断.例1.如图1,质量为m_1的球1以初速度V_1沿光滑水平面运动与静止的、质量为m_2的球2发生弹性正碰,试求碰后两球的速度?
Dialectical materialism believes that: General and special are dialectical unity. Any particularity contains generality and generally exists in each speciality. The dialectical relationship between general and special inspires us to solve problems well. Special and general-to-general transformations. The following uses the example to talk about the application of the important transformational method of special and general transformation in the matter understanding. First, the general interpretation of the writing solution of many special physical problems has a general meaning. , Deductively debating the conclusions of the typical case can make us more specific about things, so that the thinking rises from abstract to concrete. Moreover, because the typical special cases are often common, the conclusions obtained from the deduction are very large. The practicality. Remember these conclusions, you can quickly determine some of the physical problems. Example 1. Figure 1, mass m_1 of the ball 1 with the initial velocity V_1 along the smooth level of motion and static mass m_2 ball 2 When elasticity happens, try to hit the speed of two balls?
