1. Based on historical facts, a preliminary understanding of the fundamentals of modern experimental science, an understanding of experimental contributions to the development of physics.2. By understanding qualitative points, we understand the characteristics of physical models in physical research, and understand the role of physical models in the study of the laws of nature.3. Experience the experimental process of linear motion at a uniform variable speed, understand displacement, velocity and acceleration, understand the law of linear motion at a uniform variable speed, and understand the role of experimentation in discovering the laws of nature.4. He can use patterns and drawings to explain equal linear motion at variable speeds and understand the importance of mathematics in studying physical problems.
