1牛顿运动定律是整个动力学的基础,是高中物理的核心内容之一.知识的综合性较强,能力要求也较高,一直是高考的热点.解题时不要为题目所设的复杂情景所迷惑,应静下心来对题目进行分段、分步地分析,就能找到解题的路径.例1某兴趣小组设计了如图1所示的玩具轨道,其中“2008”四个等高数字用内壁光滑的薄壁细
1 Newton’s law of motion is the foundation of the whole dynamics, and is one of the core contents of high school physics. The comprehensive knowledge is strong and the ability requirement is also high. It has always been a hot spot of the college entrance examination. Do not set complicated scenarios for the topic when solving problems. Confused, should be calm down to the subject of segmentation, step-by-step analysis, you can find the path to solve the problem. Example 1 An interest group designed the toy track shown in Figure 1, in which “2008” four Contour figures with smooth thin walls
