牛顿第二定律是整个动力学的核心内容,也是历年高考频繁考查的内容之一.它定量地确定了力和运动的关系,并贯穿在力学和电磁学中,是高中物理的主干知识之一.综观近几年的高考,关于牛顿第二定律,它主要考查的是在匀加速直线运动和曲线运动中的应用,包括天体运动、带电粒子在匀强? Newton’s second law is the core content of the whole dynamics, and it is also one of the contents of frequent examinations in the college entrance examination over the years. It quantitatively determines the relationship between force and movement, and runs through mechanics and electromagnetics. It is one of the main knowledge of high school physics. Looking at the college entrance examination in recent years, regarding Newton’s second law, it mainly examines the application of uniform acceleration and linear motion, including the movement of celestial bodies, and the uniformity of charged particles.
