通常讨论的二体正碰撞过程中，由于碰撞前后两个物体都在同一直线上运动，不存在两者之间的切向滑动磨擦力．如果不是正碰撞，例如在碰撞前的瞬间这两个物体有横向的相对运动，在碰撞的接触过程中两者间便会有滑动摩擦力ｆ出现．当ｆ与纵向碰撞力Ｎ在数量级上相差不大时，其作
Usually discussed in the two-body positive collision process, because the two objects before and after the collision are moving in the same straight line, there is no tangential sliding friction between the two. If it is not a positive collision, for example, the two objects have a lateral relative movement at the instant before the collision, and there will be a sliding friction force f between the two during the collision. When f and the longitudinal collision force N are not much different in magnitude, it is
