牛顿第二定律是力学的基本规律,是力学的核心知识,在整个物理学中占有非常重要的地位,是高考命题的热点。近几年来的高考物理试题,每年都有涉及本专题的知识,各种题型均有,侧重于考查物体的受力和运动情况的分析及计算,而且与实际紧密联系命题。下面归类例析,供复习参考。1隔离 Newton’s second law is the basic law of mechanics, it is the core knowledge of mechanics, occupies a very important position in the entire physics, and is the hot spot of the college entrance examination proposition. In recent years, college entrance examination physics test questions each year involves the knowledge of this topic, all kinds of questions have, focusing on the examination of the object’s stress and movement of the analysis and calculation, and close contact with the actual proposition. The following classification analysis example for reference review. 1 isolation
