中学物理教科书中,将实际中背、抱、提、扛、抬着物体运动时,对物体做功的事实释为不做功,忽略了物理力学入门中功能转换的核心内容及动能势能的产生过程分析,本文以人教版八年级物理教材讲解内容为依据,分析诠释中学物理教材中功与能的内容。通过日常生活中实践和实验、观察与感受、思考及例题学习,调整教学讲解策略,系统解释了功和能、功能转换及守恒定律等具体教学内容。
Middle school physics textbooks, the actual back, hold, mention, carry, lift the object movement, the fact that the work done on the object is not done, ignoring the introduction of physical mechanics in the core functions of the conversion and kinetic energy potential of the process of analysis This essay is based on the contents of the eighth grade physics textbook of the PEP to analyze and explain the contents and functions of the middle and high school physics textbooks. Through daily practice and experiment, observation and feeling, thinking and example study, adjusting teaching and explaining strategies, the system explains the specific teaching contents such as power and function, function conversion and conservation law.
