参照物就是判断物体运动和静止时,被选作标准的假定不动的物体.我们常说物体是运动的或是静止的,是拿被研究的物体与参照物比较的结果.具体的讲:是看被研究的物体与参照物之间的位置变化,位置改变了物体就是运动的,位置不改变物体就是静止的.看来物体的运动和静止是相对于参照 The reference object is a hypothetical object that is selected as the standard when judging whether the object is moving or stationary. We often say that the object is moving or stationary. It is the result of comparing the object being studied with the reference object. Specifically: It is to see the change in position between the object being studied and the reference object. The position change is that the object is moving, the position does not change the object is still. It seems that the movement and the static of the object are relative to the reference.
