Static and Kinetic Friction
If you try to slide a heavy box resting on the floor,you may find it difficult to get the box moving.Static friction is the force that is acting against the box.If you apply a light horizontal push that does not move the box,the static friction force is also small and directly opposite to your push.If you push harder,the friction force increases to match the magnitude of your push.There is a limit to the magnitude of static friction,so eventually you may be able to apply a force larger than the maximum static force,and the box will move.The maximum static friction force is sometimes referred to as starting friction.We model static friction,F­­static,with the inequality Fstatic m­s N where m­s is the coefficient of static friction and N the normal force exerted by a surface on the object.The normal force is defined as the perpendicular component of the force exerted by the surface.In this case,the normal force is equal to the weight of the object.

动摩擦与静摩擦的实验,具体qq上说

物理实验为：

剩下的你就自己思考吧

这段话主要是讲静摩擦力总是阻碍物体的移动的，静摩擦力在达到最大值之前会随着水平外力的增加而一直增加，直到水平外力大于最大静摩擦力，这时物体才能移动。放置于水平面上物体的最大静摩擦力在摩擦因素不变的情况下，只与物体质量大小有关，成正比关系，即正比于摩擦因素μ。...

这段话主要是讲静摩擦力总是阻碍物体的移动的，静摩擦力在达到最大值之前会随着水平外力的增加而一直增加，直到水平外力大于最大静摩擦力，这时物体才能移动。放置于水平面上物体的最大静摩擦力在摩擦因素不变的情况下，只与物体质量大小有关，成正比关系，即正比于摩擦因素μ。
