知识载体、能力立意是高考命题一贯坚持的理念。这种理念的直接表现就是利用主干知识考查学生的五大能力。在高考中的主干知识主要有:平衡规律、牛顿运动定律、动能定理、机械能守恒定律、功能关系等。这些规律的应用跨度较大,从命题内容看,主要表现为力、电方面的综合应用。在解答这些主干题目时,往往都需要用到受力分析,唯有做好受力分析方能保证后面的思路畅通。因此受力分析也被称为一把打开物理题库的金
Knowledge carrier, ability conception is the concept of college entrance examination has consistently adhered to. The direct manifestation of this concept is to use the knowledge of the backbone to examine the student’s five abilities. Main knowledge in the college entrance examination are: balance law, Newton’s law of motion, kinetic energy theorem, the law of conservation of mechanical energy, functional relationships. The law of application of a larger span, from the proposition content, mainly for the force, the comprehensive application of electricity. In the answers to these main topics, often require the use of force analysis, the only way to do a good job of stress analysis to ensure that the back of the ideas flow. Therefore, force analysis is also known as a gold open physical exam
