竖直平面内的圆周运动和机械能守恒定律是高考重点考查内容之一,也是学生难以掌握的内容.此类题型往往考察了能量的转化问题,有时候却会忽略力学问题,本文通过实例探究,通过能量转化与力学分析两维角度方式,寻找解决此类问题的一般性解决思路和规律.
The circular motion in the vertical plane and the law of conservation of mechanical energy are one of the key examinations of the college entrance examination and are also difficult to grasp by the students.This type of questions often examines the energy conversion problems and sometimes neglects the mechanical problems. Through energy transformation and mechanical analysis of two-dimensional approach, to find a solution to such problems general solution ideas and laws.
