动力学是高中物理教学中的重点教学内容之一,让高中生理解和掌握动力学知识,有利于提高学生物理知识水平,更好地应对高考。综合当前高中物理教学的实际情况来看,很多学生对动力学知识掌握得不扎实、不透彻。究其原因,主要是刚进入动力学知识学习时,学生便进行固定杆弹力知识的学习,其中涉及动力关系方面的知识,使学生在不了解动力关系的情况下,难以准确分析固定杆的弹力,明确固定杆的弹力方向。所以,规范、合理地进行固定杆的弹力分析教学案例研究是非常必要的。
Kinetics is one of the key teaching contents in high school physics teaching. It enables high school students to understand and master kinetic knowledge, which helps to improve students’ physical knowledge level and better cope with college entrance examination. According to the current actual situation of high school physics teaching, many students do not grasp the dynamics knowledge solidly and thoroughly. The reason is mainly that when students first entered kinetic knowledge learning, students learned the knowledge of fixed-rod elasticity, which involved the knowledge of dynamic relationships, which made it difficult for students to accurately analyze the elasticity of the fixed-rod without understanding the dynamic relationship , A clear direction of the elastic rod fixed. Therefore, it is very necessary to conduct a case study of the elastic analysis of the fixed rod in a reasonable and reasonable manner.
