对在运动进行描述时,需要选取一定的参照系,所选择的参照系不同,那么对物体运动的描述就会不同。要判断一个参照系是否为惯性参照系,需要通过实验来验证。而在对牛顿第一定律进行表述时,我认为要判断所选取的参照系是否为惯性系,其判断的依据就是牛顿第一定律是否成立。 To describe the movement, we need to select a certain frame of reference, the selected reference frame is different, then the description of the object movement will be different. To determine whether a frame of reference is an inertial frame of reference, it needs to be verified experimentally. In the expression of the first law of Newton, I think to determine whether the selected reference system is inertial, the basis for its judgment is whether Newton’s first law holds.
