在解物理习题时,其必要条件题中并未明确给出,而是隐含在字里行间。怎样才能快速、准确地找出这些隐含条件呢?同学们应注意以下几点。一、知道一些提法的含义课本上经常用一些固定的提法来说明某些现象。这些提法中的某些词语由于已约定俗成,所以具有确定不变的含义,知道了这些提法的含义,就等于知道了隐含条件。如“一物体在光滑面上运动……” When solving a physics problem, it is not explicitly given in the necessary conditions but it is implied between the lines. How can we find these implied conditions quickly and accurately? Students should pay attention to the following points. I. Know the meaning of some references There are often fixed references to some phenomena in textbooks. Some of the words in these references have a definite meaning because they have been adopted, and knowing the meaning of these references is equivalent to knowing the implicit conditions. Such as “an object moving on a smooth surface...”
