Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
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...
Are centripetal force and mass directly related? Is centripetal force contact or noncontact? Why does centripetal force decrease when mass is increased? Does string tension cause centripetal force? Does the tension of a pendulum provide centripetal force? Is centripetal force constant in non-uniform c...
A Lagrange point is a region of space where gravitational and centripetal forces balance so that an object, such as a spacecraft or anasteroid, can remain stationary relative to a larger body, such as Earth. The Lagrange points are particularly useful for parking space probes. Does Earth have...

These forces allowed the participants to reimagine the space of language teacher education as inclusive of different sites, experiences, and objects. Some of these sites are exclusive of language education such as “instituto[s]” (Fig. 6). This centripetal conception of space also remarks the ...
The monocot cambium forms a continuous ring of meristematic cells that produce derivative cells mostly centripetally, where they differentiate into the cells forming vascular bundles and the surrounding ground tissue (Figure 3g), while the few cells that are produced in the opposite direction ...
