在练习的过程中经常会遇到内容和情景相似但解法、思路和答案却不相同的问题,通过对这些相似问题的整理、归纳、分析和比较,不仅能培养学生的审题能力,而且能加深对所学知识的理解,从而达到融会贯通的目的. 例1 如图1所示,质量均为m的两小球,分剐用长为l的细线拉着和固定在长为l的轻杆一端,让两球在竖直面内做圆周运动.则它们能过最高点的线速度大小应满足( ) In the process of practice, you often encounter problems with similar content and scenarios but with different solutions, ideas, and answers. By collating, summarizing, analyzing, and comparing these similar issues, you can not only develop students’ problem-solving abilities, but also deepen The understanding of the learned knowledge, so as to achieve the purpose of integration. Example 1 As shown in Figure 1, the quality of the two balls are m, the childbirth is pulled with a thin line of length l and fixed in the length of l light bar At one end, let the two balls do circular motion in the vertical plane. Then the linear velocity they can reach the highest point should be sufficient ()
