查阅近年来各地的中考试卷,发现不少试卷上都有涉及惯性大小的选择题,但笔者觉得在初中阶段专门讨论这类问题并不太合适,现谈几点看法题目:下列有关物体惯性的说法,正确的是:(A)物体运动速度增大,其惯性也增大.(B)物体运动速度减小,其惯性也减小.(C)物体静止时,其惯性最大.(D)物体的惯性与其运动状态无关.
Looking through the examination papers in various places in recent years, I found that many papers have multiple choices involving inertial size, but I feel that it is not appropriate to discuss such issues in the junior high school stage. Let’s talk about some topics: The following questions about the inertia of objects It is correct to say that: (A) The object’s movement speed increases and its inertia increases. (B) The object’s movement speed decreases, and its inertia also decreases. (C) When the object is stationary, its inertia is maximum. (D) The inertia of an object has nothing to do with its movement state.
