笔者在教学中探索、研究、总结出求解具有相同加速度的两物体间相互作用力的一般规律 ,现整理如下 ,供读者参考 .一、规律的推导问题　如图 1所示 ,A、B为两个并排紧贴图 1着放在光滑水平面上的物体 ,在水平恒力 F1、F2 的作用下做匀加速运动 .已知两物体的质量分别为m A、m B. In the teaching, the author explores, studies, and summarizes the general laws for solving the interaction forces between two objects with the same acceleration, and is now organized as follows for readers’ reference. First, the law derivation problem is shown in Figure 1, A and B are two Side by side close to the figure 1 with an object placed on a smooth horizontal surface, under the action of horizontal constant force F1, F2, uniform acceleration movement. Known mass of the two objects are m A, m B.
