“能量”概念的教学在高中物理教学中有着十分重要的地位,“能量”概念的内涵非常丰富,甚至有些“深奥”.在现行高中物理教学中,常常会看到学生因对能量的系统性和相对性的认识不足,导致在应用能量概念和能量规律时常犯迷糊.本文针对这一现象,从实例出发,对能量的系统性和相对性加以阐述,以期引起在高中物理教学中对其的重视. The teaching of the concept of “energy” plays a very important role in physics teaching in senior high school, and the connotation of “energy” is very rich and even some “esoteric.” In the current high school physics teaching, students are often seen Due to the lack of understanding of the systematic and relativistic energies, it leads to confusion in the application of energy concepts and energy laws.In this paper, starting from an example, this article elaborates the systematic and relativistic aspects of energy, Its emphasis on physics teaching.
