在学过摩擦力知识后,学生知道静止在水平地面上的物体,施加的水平推力至少为物体与地面间的最大静摩擦力时,物体才发生相对运动.受此影响,很多学生认为推力大于最大静摩擦力时,物体就发生相对滑动,以此作为判断物体间是否发生相对滑动的物理原因.江苏省无锡市2006年秋学期高一物理期末考试试卷最 After learning the knowledge of friction, the students know that the object is still on the level of the ground, the horizontal thrust is at least the maximum static friction between the object and the ground, the object will only occur relative motion. Affected by this, many students believe that the thrust is greater than the maximum static friction When the force, the object is relatively slipping, as a physical reason to determine whether the relative sliding between the objects.
