两个叠放着的物体运动的分析,高职的学生往往感到棘手。两个物体在运动过程中有的没有相对滑动,有的存在相对滑动,正确判断两物体是否发生相对滑动是解答这类问题的关键。以下举例说明。 Analysis of the motion of two superimposed objects is often tricky for higher vocational students. Some objects do not slide relative to each other during the movement, and some have relative sliding. Correctly determining whether two objects are moving relative to each other is the key to solving such problems. The following is an example.
