一、本月知识学习指要牛顿第三定律给出了相互作用的两物体间作用力的关系．在应用牛顿定律解题时，首先应确定研究对象，并对其进行受力分析和运动分析，要特别注意加速度的方向与合外力的方向相同这一要点．二、练习题精选１．下列说法中正确的是［］Ａ．质量较大的物体... 1. This month’s knowledge study means that Newton’s third law gives the relationship between interaction forces between two objects. When applying Newton’s law to solve a problem, we must first determine the research object, and perform stress analysis and motion analysis on it. We must pay special attention to the point that the direction of acceleration is the same as the direction of external force. Second, practice questions featured 1. The correct thing in the following statement is []A. Larger objects...
