摘要
提出一种模型，把物体间的切向力的作用区分为推动作用和摩擦作用，其中摩擦作用做正功，正是这个正功才使物体的内能增加，从而完整地解释了“摩擦生热”现象。
A physical model is introduced, in which the action of force caused by relative motion between contact objects is divided into the action of push and the action of friction. Only the action of friction does positive work and contributes to internal energy. Thus the thermal effect resulting from friction does is explained completely.
