“纸带问题”是运动学规律的综合应用,结合了实验和生活实际,是学生对实验数据分析处理的很好的训练题.是高中物理的重点和难点,在平时考查中是必考内容,在高考中也是热点知识;并且在物理实验和平抛运动题目中有广泛的应用.所以我们应该熟练掌握纸带类题目.一、“纸带问题”主要研究内容(一)纸带的运动性质:匀速直线运动、匀变速直线运动、非匀变速直线运动.(二)纸带上某点的瞬时速度及验证机械能守恒实验,
“Paper tape ” is a comprehensive application of the laws of kinematics, combined with the experimental and practical life, is a good student of experimental data analysis and training of the problem is the focus of high school physics and difficult, in the usual test is bound to Test content, is also a hot spot in the college entrance examination knowledge; and in the physical experiment peace throwing the topic of sports have a wide range of applications, so we should be proficient in the topic of paper tape class. “Paper tape ” the main research content With the movement of the belt: uniform linear motion, uniform linear motion of variable speed, non-uniform speed linear motion. (B) the instantaneous speed of a point on the tape and verify the conservation of mechanical energy experiment,
