1引言本刊2004年第2期中一文《对高中物理教材“机械能守恒定律”一节的思考》(以下文[1]),认为机械能守恒具有相对性.首先文[1]提出的这个观点值得商榷.文[1]认为机械能在一个惯性参照系守恒,在另一个惯性系就不一定守恒,这样的观点曾在《大学物理》杂志上引起广泛的争议(文[2 1 Introduction The article in the 1st issue of the Chinese article entitled “Conservation of the mechanical energy conservation section” for high school physics textbooks (herein after [1]) considers the conservation of mechanical energy to be relativistic. This viewpoint proposed in [1] is worth first. Shang Yi. Wen [1] believes that mechanical energy is conserved in an inertial frame of reference and not necessarily conserved in another inertial frame. This view has caused widespread controversy in the journal of College Physics (Article [2].
