1、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。

2、Notice that the acceleration, the centripetal acceleration is linear in r.
在此注意，向心加速度與r是成正比的。

3、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。

4、And we can calculate now what the centripetal acceleration is.
這樣我們，就能求出向心加速度。

5、So what I get now is must be m times the centripetal acceleration Hey! That looks very familiar.
則現(xiàn)在,必然等于m乘以向心加速度,嘿，看起來太眼熟了。
