相信学生们都知道,中学物理中运算中最为庞大的莫过于运动学的题。这部分的题由于要考虑的变量多,加之所需要分析的过程多变,如果再是一道涉及多个对象的多个运动过程的综合题,就会出现一大堆的物理量,如M1M2M3……,T1T2T3……,△V,V0,M1,S,L,N等等。若是在考试中遇到这种题,轻则得数算错,略扣几分,重则满盘皆错,全军覆没。浪费时间不说,会使自信心受挫,影响考试的状态甚至发挥失 I believe that students all know that the biggest problem in middle school physics is in kinematics. This part of the question due to many variables to be considered, coupled with the need for analysis of the process is changeable, if it is a comprehensive problem involving multiple motion processes of multiple objects, there will be a lot of physical quantities, such as M1M2M3...... , T1T2T3 ..., △ V, V0, M1, S, L, N and so on. If such a problem is encountered in the examination, it may be counted as a mistake, a slight deduction, or as a mistake. A waste of time does not say that it will frustrate self-confidence, affect the status of the exam or even play a role.
