031牛顿第一定律（031 Newtons first law） I. teaching objectives 1. learn the content of Newtons first law in physical knowledge, correctly understand the relation between force and object motion, and grasp the concept of inertia. A correct understanding of objective things need 2. people through the process of understanding from the outside to the inside, from partial to full long time. Through the study of this section, we should let the students set up the correct epistemological point of view, and realize the long-term and arduous nature of peoples understanding of the world. 3., physics experiment is the method of scientific research. It is the foundation of Galileos correct relation between the force and the object movement to make reasonable abstraction and carry on ideal experiment to the actual problem. We should learn the methods of scientific abstraction and apply it to future research in physics. Two, key and difficult analysis 1., the focus of this section is the correct understanding of the relationship between object motion and force. In the case of an object without force, it should maintain a uniform linear motion state or static state. Through the study of Newtons first law, we can deepen our understanding of the concept of inertia. 2., common sense of life leads to incorrect understanding of the relationship between force and movement. Through teaching, it is necessary for students to overcome traditional ideas and form correct understanding, which requires a certain amount of effort. Three, teaching aids 1. explain Galileos ideal experiment device, self made guide rail and small ball. 2.. The air cushion rail and slider for the uniform rectilinear motion of the object without resistance. 3. demonstrate the inertia of the car and the wood block. Four, the main teaching process (1) introducing new courses Introduce the position of this chapter: in the first chapter, we study the force problem of an object in the state of motion in a stationary or uniform li
