一、教学过程和方法的比较摆的振动是生活中常见的现象，其中蕴含着丰富的物理知识。这些知识容易理解，实验操作简便，实验现象容易观察和再现，实验中的参数、误差也容易控制。因此，有关单摆的知识是各国初等物理教材中的重要内容。在我国，单摆知识的讲授是在高一年级（相? First, the comparison of teaching methods and methods The vibration is a common phenomenon in life, which contains a wealth of physical knowledge. This knowledge is easy to understand, experimental operation is simple, easy to observe and reproduce the experimental phenomena, the experimental parameters, errors are also easy to control. Therefore, the knowledge of the pendulum is an important part of elementary physics textbooks in various countries. In our country, pendulum knowledge is taught in the first grade (phase?
