摘　　要：针对分析力学教学环节中学生普遍存在的问题,本文从2个典型的物理问题——降落伞与双摆模型入手,通过一题多解与对比学习的形式,呈现2种力学在处理相同物理问题时的差异.引导学生思维从经典牛顿力学向分析力学过渡,使其能够尽快融入到分析力学的学习中去.同时在教学过程中引入适当的数值计算,进一步加深学生对具体物理问题的理解.Aiming at the common problems of students in the teaching of analytical mechanics,this paper starts with two typical physical problems(parachute problem and the double pendulum model),and presents the differences between the two mechanics in dealing with the same physical problem through the form of multi-solution and comparative learning.To guide students'thinking from classical Newtonian mechanics to analytical mechanics,so that they can be integrated into the study of analytical mechanics as soon as possible.At the same time,the appropriate numerical calculation is introduced in the teaching process to further deepen students'understanding of specific physical problems.
