A liquid mirror telescope (LMT) may be made by rotating a reflectiveliquidmetal,such as mercury. The mirror surface assumes a paraboloid shape because the centripetal force depends on the square of the velocity. Because of this, the height of the spinning liquid metal is proportional to the squ...
Centripetal force: This force is acting on the object towards the center of the circle. Centrifugal force: This force is acting on the object away from the center of the circle. The magnitude of both the forces are same. It is given by, ...
求向心力的公式就是向心力(centripetal force)没错,答得好再加悬赏分 真正问题是:what forces act on you were you at the centre of the earth? 相关知识点: 试题来源: 解析 向心力是没有公式的!有公式就是骗人的!为什么呢?因为向心力的定义就是: 作圆周运动的物体,它运动的时候的合力指向圆心,这个合...

What will the acceleration be if the force is halved? Force of impact is the force of What does net force mean? What is net force? Explain. How is force related to momentum? Two forces pull on an object at the same time. Their resultant force is greatest when the angle between the ...
"The difference between centripetal and centrifugal force has to do with different 'frames of reference' — that is, different viewpoints from which you measure something," said Andrew A. Ganse, a research physicist previously at the University of Washington. "Centripetal force and centrifugal force...
it depends on what you mean by real. what is a force? here is a quick overview of what a force is. i previously talked about real vs. non-real forces. for me, i say that if the force is essentially one of the 4 fundamental forces then it is "real". with this definition, ...
Inline Side-by-side Side-by-side Markdown There is no centripetal force here at all, actually, as there is no force pointing towards the center of the disk. In an inertial frame of reference there isn't a force pointing radially outwards either. So why does the particle move outwards?
You use the term "normal force". What do you mean by that in this context? How would you say that it explains how the train stays on the track? This is what I mean: This happens anytime the train engine turns. Or, to better say, when the rails change course, and so th...
Your data is in a sorted array and I'll assume you swap the new two if needed so also sorted, so a. if you want to keep it in place then use a form of insertion sort; b. if you want to have it the result in another array do a merging by copying. With the small ...
