一根手指的弹击足够使一个气球加速离去，当气球运动时，一点动力，甚至空气的摩擦力可以很快使它慢下来。
The flick of a finger is enough to make a balloon accelerate away. When moving, it has little momentum and even the friction of the air quickly slows it up.
木板哪怕沾了一点水，局部的摩擦系数就会改变。
A little bit of water on the plank would locally make the friction coefficients larger.
到了某个点，“压力压倒了摩擦力，”进行这次地质勘察的地球物理学者Rosss.Stein说，然后断裂就产生了。
At some point, said Ross s. Stein, a geophysicist with the geological survey, "the stress overwhelms that friction," and a rupture occurs.
但如果在门铰链突然断掉之后，由于门框突然倾斜而门板没有倒塌，这个门板可能会由于一小点摩擦力而暂时支撑住了。
But if after the door hinges snap but the door cannot fall because the frame suddenly skews, the door might get temporarily held in place by friction, by a pinch.
它主要解决物体所受摩擦力，分离点位置以及其他相关的流体动力学参数预报问题。
It mainly solves the questions of the friction, location of the separating and the forecast of dynamics parameter.

Curved traveling crawler machine is relied on a frictional resistance between the crawler treads and ground. This paper gives the calculation of curved traveling on three-crawler machine.
摩擦力就是各个啮合点被剪断时的阻力。
The friction force is each meshing point cut off resistance.
在这样的情况下，他会不惜任何代价来换取那怕只是一点儿摩擦力。
In such a situation he would give anything for the sake of just a little friction force.
