对摩擦力作功问题中一个谬误的分析

ANALYSIS OF A MISUNDERSTANDING ON THE WORK DONE BY FRICATIVE FORCE

本文由一特例出发,对产生的认为摩擦力也可能具备有保守力的特性的误解,进行简明分析,从而确认摩擦力是非保守力,摩擦力场是非保守力场.

A brief explaining on a misunderstanding that friction force maybe has some features of conservative force is given from a special example.Then some conclusions on the friction force field is un—conservative field.
