[教材]人民教育出版社高中课程标准实验教科书物理选修3-4第十一章第4节。[课时]1课时(45分钟)一、教材分析《单摆》是在已学习简谐运动及其特征的基础上进行的,可说是简谐运动的延伸。简谐运动是最简单、最基本的机械振动,而单摆作为简谐运动的一个典型例子,是从生活实例中抽象出的物理模型,与人们的日常生活、生产实践、科学研究有着密切的关系。 [Textbook] People’s Education Press high school curriculum standard experiment textbook physics elective 3-4 eleventh chapter fourth. [Class] 1 class (45 minutes) First, textbook analysis “pendulum” is based on learning simple harmonic motion and its characteristics based on, it can be said is an extension of harmonic motion. Simple harmonic motion is the simplest and most basic mechanical vibration. The pendulum, as a typical example of simple harmonic motion, is a physical model abstracted from life examples. It has close relationship with people’s daily life, production practice and scientific research relationship.
