If the centripetal acceleration is larger than 10 then, of course, the string will be tight.(若向心加速度0,則此時繩子會繃緊。)

Do not confuse ever the tangential acceleration, which is along the circumference, with a centripetal acceleration.(但是別把這個切向加速度，它是沿著圓周的，和向心加速度混淆。)

This can be called centripetal radiation.(這可稱之為向心輻射。)

Wenchuan earthquake, we have not destroyed, while China's pride, and the centripetal force rapidly.(汶川地震沒有摧垮我們，卻使中國人的自豪感、向心力迅速提升。)

When the dog shakes, centripetal forces pull the water away.(狗一抖動，向心力就使水脫身而出。)

The comparison shows the centripetal tendency of the complements.(比較之后，可以看出補語演變過程中的向心趨勢。)

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,依然毫無商量余地。)

The happy blood is unable the backflow centripetal dirty.(幸福的血液無法回流向心臟。)

Furthermore, we compare the centrifugal flow with the centripetal flow of axisymmetrical passing flow.(并對軸對稱過流流動的外向流和內向流進行了比較。)

And there has to be here a force on the system, the gravitational force, which is the same as the centripetal force.(這個系統中，存在重力，和向心力相等。)
