centripetal

If the centripetal acceleration is larger than 10 then, of course, the string will be tight.(若向心加速度0,则此时绳子会绷紧。)

Do not confuse ever the tangential acceleration, which is along the circumference, with a centripetal acceleration.(但是别把这个切向加速度，它是沿着圆周的，和向心加速度混淆。)

This can be called centripetal radiation.(这可称之为向心辐射。)

Wenchuan earthquake, we have not destroyed, while China's pride, and the centripetal force rapidly.(汶川地震没有摧垮我们，却使中国人的自豪感、向心力迅速提升。)

When the dog shakes, centripetal forces pull the water away.(狗一抖动，向心力就使水脱身而出。)

The comparison shows the centripetal tendency of the complements.(比较之后，可以看出补语演变过程中的向心趋势。)

r and therefore, you require centripetal acceleration towards the center-- that is non-negotiable.(所以你需要，This，v，equals，omega，rv=ω,向心加速度,依然毫无商量余地。)

The happy blood is unable the backflow centripetal dirty.(幸福的血液无法回流向心脏。)

Furthermore, we compare the centrifugal flow with the centripetal flow of axisymmetrical passing flow.(并对轴对称过流流动的外向流和内向流进行了比较。)

And there has to be here a force on the system, the gravitational force, which is the same as the centripetal force.(这个系统中，存在重力，和向心力相等。)
