1.The resistance experienced when one body moves over another, with which it is in contact, is called the frictional force.
一个物体在和它接触的另一物体上移动时所受的阻力叫做摩擦力。
2.If, however, this object wants to go in this direction - which I do not know-- then the frictional force has to be put in this direction.
不过如果物体有下滑的趋势，我不知道-，那么摩擦力，就会向上。
3.The correlation of average frictional resistance coefficient is the same with that of no rolling motion.
