高三物理复习中常常遇到这样一类选择题,它们具有计算题的一般特征,给出了详细的数据,让你去求解某一个物理量.但它们又提供了该物理量的四种不同表达式,让你进行选择,当你打算通过计算的方法进行处理时,往往又很难下手.其实,通过分析发现,这类选择题的意图并不让你直接求解,考查你的计算推理能力,而是想检验学生的思维灵活性,在陌生的题
In the senior high school physics review, we often encounter such a type of multiple choice questions, they have the general characteristics of the calculation problems, gives the detailed data, let you go to solve a certain physical quantity.But they provide four different expressions of the physical quantity, Let you make a choice, when you intend to deal with by calculation method, often difficult to start .In fact, through the analysis found that the intention of such a multiple-choice question does not let you directly solve, examine your ability to calculate reasoning, but Want to test the students’ thinking flexibility, strange topic
