Physics is a natural science based on experiments. Looking back at the process of the emergence and development of physics, we can see that physical experiments occupy an extremely important position from beginning to end. Both the establishment and development of classical physics and the progress of modern physics are closely related to physical experiments. 1 the position and function of experiment in physics teaching

1) Experiments can combine physics teaching theory with practice, stimulate students' interest in learning, guide students to explore problems, and stimulate students' desire for knowledge, thus mobilizing their initiative and enthusiasm to learn physics well and guiding them to love science.

2) By strengthening experiments, students can not only have a certain perceptual knowledge, but more importantly, they can further understand how physical concepts and laws are based on experiments, thus effectively helping students to form concepts, deduce laws, master theories and correctly and profoundly understand physical knowledge.

3) Cultivate students' observation ability, thinking ability, self-study ability and the ability to find, analyze and solve problems through experiments; Cultivate students' good experimental methods, basic experimental ability and practical ability, and further cultivate students' independent working ability and innovative ability on this basis.

4) Cultivate students' rigorous scientific attitude, scientific thinking method and rigorous scientific style in scientific research through experiments, and gradually learn the basic scientific methods in physical research.
