功能关系是中学物理中最基本、最重要的规律,是贯穿整个高中物理的主线之一,在历年的高考中,从考点上看,这部分考题将功能关系与牛顿运动定律、曲线运动、电磁学等方面知识结合到一起,物理过程复杂,综合程度较高;从情景上看,这部分考题密切联系生活实际、现代科学技术,具有较强的新颖性和探究性.因此,该部分试题能够很好的考查学生的探究能力、建模能力和分析综合能力,从而备受高考命题者的关注,成为试题中经 Functional relationship is the most basic and most important law in middle school physics. It is one of the main lines of physics that runs through the entire high school. In the college entrance exams over the years, from the test sites, this part examines the relationship between functional relationships and Newton’s laws of motion, curvilinear motion, Learning and other aspects of knowledge together, the physical process is complex, a high degree of integration; from the scenario point of view, this part of the exam closely linked to the reality of life, modern science and technology, with strong novelty and inquiry.Therefore, Very good examination of students’ ability to explore, modeling ability and analysis of comprehensive ability, thus highly concerned about the college entrance examination proposition, a test of the
