链条桌边下落问题的探究

DISCUSSIONS ON THE CHAIN FALLING ALONG THE TABLE EDGE

链条的力学问题在物理学的发展过程中受到人们的关注,并与实际工程应用有着密切联系。"下落链条"作为典型的模型,经常被用来考察学生对于动量守恒和功能原理的理解和应用。然而,对于链条下落运动的认识依然存在着诸多分歧。本文将讨论"链条桌边下落"这一过程中分离点的问题。

Mechanics problems of chain have attracted attention of people in the development of physics.It has close ties with the engineering application.＂Falling chain＂,as a typical model,is often used to check students＇understanding in the principle of conservation of momentum and kinetic energy.However,there are still controverse unsettled about this problem.This article will discuss the separation point in the process of falling chain along the table edge.
