传送带问题具有理论联系实际,综合性较强的特点,是高中物理的热门课题之一,在各类模拟题和高考题中屡见不鲜。但这类题大都具有情景模糊,条件隐蔽,过程复杂的特点,而能量分析尤其是其中的难点。本文将从做功和能量转化与守恒两个方面探讨传送带问题中蕴藏着共同的物理规律。一、传送带中的功能关系
Conveyor belt problem with the theory of practice, the characteristics of a strong comprehensive, high school physics is one of the hot topics in all kinds of simulation questions and college entrance examination questions are not uncommon. However, most of these questions have the characteristics of blurred scenes, hidden conditions and complicated processes, and energy analysis is especially difficult. This article will discuss the common physical laws in the issue of conveyor belt from two aspects of work and energy conversion and conservation. First, the functional relationship in the conveyor belt
