Research On The Teaching Of Knowledge Of Conservation Of Mechanical Energy On Physics In Senior High School

The knowledge of mechanical energy conservation plays a very important role in the development of physics. The teaching of the knowledge points has always been an important teaching content of high school physics and mechanics.Firstly, on the basis of physics learning difficulties, law teaching theory as a guide of high school physics mechanical to conservation knowledge for knowledge analysis, experimental research; through literature research summarized the students to physical and mechanical can before the learning of knowledge related to the conservation of concept. Then through the questionnaire survey, to understand the students of physical and mechanical to conservation chapter "work and power, potential energy, kinetic energy and theorem of kinetic energy, mechanical to conservation theorem" knowledge learning grasp the situation and difficulties in learning situation. Finally, on the basis of the above study and investigation study of proposed on physical mechanical energy conservation knowledge teaching suggestions, expectations of high school physics teaching reference value.
