力学模块是高中物理的支撑模块,历年高考都非常重视对力学分析能力的考查.力学过程分析的关键在于建立过程模型,过程模型建立是否正确直接决定着解题的方向和结果.运用特征模型(轻绳带球或杆带球做圆周运动模型、子弹打木块模型、类平抛运动模型等)建模是常用建模方法,实践表明复习到一定程度,适当运用常见模型进行分析能事半功 Mechanical module is a high school physics support module, over the years the college entrance examination attaches great importance to the ability of mechanical analysis.Mechanical process analysis is the key to establishing a process model, the process model is established directly determines the direction and result of the problem solving.Using the feature model Light rope with a ball or a tape ball to make a circular motion model, bullet playing wood model, class flat throw motion model, etc.) modeling is a common modeling method, practice shows that review to a certain extent, the appropriate use of common models for analysis of energy half Work
