If indeed the friction coefficient is independent of surface area, then when I tilt them they should start to slide roughly at the same angle. 若摩擦系数真的,与接触面积没有关系,那么两者下滑时的角度,应该基本相当。
And as I increase the tilt this frictional force will get larger and larger and larger and then there comes a time that the object will start to slide. 随着倾斜度的变大,摩擦力,会越来越大,加到某一程度,物体会开始下滑。
Since TILT is designed primarily to help you with research skills, the next thing to think about is how and where to start your research. 由于TILT主要是为了帮助你进行研究而设计的,下面要考虑的就是怎样,从哪里开始你的研究。
