物理是一门自然学科,也是一门实验学科,还是一门崇尚理性重视逻辑推理的学科。物理学的发展孕育了技术的革新,促进了物质生产的繁荣,改变了人类的生产和生活方式,推动了社会的进步。如今我国神舟系列飞船的顺利升空,以及美国海军试射电磁炮已成为人们关注的焦点,同时在高考试题中,也能见到这些热门话题的身影,同学们一遇到这类问题就感到头痛没有思路。解决这类问题,教师就要教会学生利用已有的物理模型解决问题,若要能够使学生熟练地运用物理模型解决问题,教师应当做到以下几点:一让学生学会归纳和建立物理模型在物理教材上有一些简单物理模型,如质点、点电荷等概念是理想物理模型,还有匀速直线运动、平抛运动、匀速 Physics is a natural discipline, an experimental discipline, or a discipline that advocates rational emphasis on logical reasoning. The development of physics has given birth to technological innovations, promoted the prosperity of material production, changed human production and lifestyles, and promoted social progress. Now that the successful launching of China’s Shenzhou spacecraft and the launching of the US Navy’s test-firing electromagnetic guns have become the focus of attention, as well as being able to see these hot topics in the entrance exams, students feel that they encounter such problems Headache no idea. To solve such problems, teachers should teach students to use the existing physical model to solve the problem, to enable students to skillfully use the physical model to solve the problem, teachers should do the following: a let students learn to summarize and establish a physical model in Physical textbooks have some simple physical models, such as particle, point charge and other concepts is the ideal physical model, as well as uniform linear motion, flat throwing motion, uniform speed
