正确认识参照物是解决机械运动问题的前提，在实际当中，只有正确地合理地选择参照物，才能对具体问题作出明确的判断．下面就有关参照物的题型归纳举例如下：一、判断物体的运动情况判断时可假想自己站在选定的参照物上去观察，看研究对象相对于参照物的位置是否发生变化，即?
Correctly understanding the reference object is the premise to solve the problem of mechanical movement. In practice, only by properly and reasonably selecting the reference object can we make a clear judgment on the specific issue. Here’s an example of the following types of questions about reference objects: 1. Judging the movement of objects When you judge, you can assume that you stand on the selected reference object and observe whether the position of the study object changes relative to the reference object.
