用物理规律分析生活现象,解决一些实际问题,既可以加深、巩固学生对物理规律的理解,又能极大的激发学生学习物理的兴趣和动力,这对于培养学生创新精神和实践能力、全面实施素质教育大有裨益。本文就运用中学物理知识分析拔河比赛中决定胜负的因素。设甲乙双方举行拔河比赛,绳子 Analyzing the living phenomena with physical laws and solving some practical problems can not only deepen and consolidate the students’ understanding of the laws of physics, but also greatly stimulate students’ interest and motivation in studying physics. This is of great significance to cultivating students’ innovative spirit and practical ability and implementing them in an all-round way Quality education is of great benefit. In this paper, we use the knowledge of middle school physics to analyze the factors determining the outcome of tug-of-war. Let both parties hold tug of war, rope
