Preliminary Study on the Teaching Mode of the Demonstration Experiment in College Physics Classroom Teaching

This paper starts from the current situation of domestic and foreign classroom demonstration experiments, then combined with the reality of laboratory in Southwest Petroleum University, and discusses the reform scheme for physics curriculum based on the classroom demonstration experiment in engineering university. At last, it focuses on the theorem of momentum and angular momentum and angular momentum conservation law, and emphasizes the important auxiliary function of the demonstration experiments in theory teaching.
