在解答物理题时 ,如果能用物理思想简化解题过程 ,就能把各部分知识有机结合起来 ,大大地提高解题速度 ,起到事半功倍作用。下面介绍一道有趣的物理竞赛题的四种解法。题目 :一只老鼠从老鼠洞沿直线爬出 ,已知爬出速度Ｖ的大小与距老鼠洞中心的距离Ｓ成反比 ,当老鼠到达老鼠洞 In solving physical problems, if you can use physical ideas to simplify the problem-solving process, you can organically combine all parts of knowledge, greatly improving the speed of problem solving, and play a multiplier role. Here are four ways to solve an interesting physics contest. Title: A mouse climbs out of a mouse hole in a straight line. Knowing that the crawling speed V is inversely proportional to the distance S from the center of the mouse hole, when the mouse reaches the mouse hole
