在高中阶段,考察惯性的时候,常会出现一类题目,就是判断一个物体A相对于另一个运动状态正在发生改变的物体B(A、B间有一定的牵连运动),由于惯性存在,物体A的运动状态将如何改变.这类题目,学生在目前的一些解答中,经常是看着答案详解好像明白,让他再做类似题目又容易出错,其实这种现象的背后是学生没有真正理解物体惯性的体现!下面我们先看两个例题,然后对比讲解,如何利用空间挤占位置快慢的方法帮助学生更好的理解惯性,已达到更加精准 In high school, when examining inertia, often a class of problems, is to judge one object relative to another state of motion is changing B (A, B have some implicated movement), due to inertia, object A How to change the state of such problems, the students in some of the current answers, often look at the answer as if to understand, let him do a similar problem and error-prone, in fact, this phenomenon is behind the students did not really understand the object Inertia embodiment! Here we look at two examples, and then contrast, how to use space to squeeze the speed of position to help students better understand the inertia, has reached more accurate
