对本刊2005年第2期刊登的《滑动摩擦力做功问题再探》一文中(以下简称文[1])对滑动摩擦力做功的剖析,笔者认为有的观点是不能成立的,因此提出下列问题来商榷.1一对滑动摩擦力做功不为零图1文[1]明确提出:一对滑动摩擦力做功一定为零.其理由是:功的位移是力的作用点的位移而非质 In the article “Reexploring the Problem of Sliding Friction Work Performed in the 2nd Issue of 2005” (hereinafter referred to as [1]), the work done on the sliding friction work, the author believes that some of the views are not valid, and therefore proposes the following: The problem is to be solved.1 The work of a pair of sliding friction is not zero Figure 1 [1] clearly states that: A pair of sliding friction work must be zero. The reason is: the displacement of the work is the displacement of the point of force rather than the quality
