This has absolutely no tangential velocity.

这绝对没有切向速度。

Her connection to this case is tangential, at best.

她与本案最多也就是一点间接牵涉而已。

Let's start with why is it a big deal to make it… stay tangential.

让我们首先谈谈为什么让它… … 保持切线是一件大事。

But we can also describe an object's rotation in terms of its tangential velocity.

我们也可以一半 以切向速度表示物体旋转。

In fact, its tangential velocity will be equal to its angular velocity, times the radius.

事实上，它切向速度将是 等于它角速度乘以半径。

Because, to get its total velocity, you add the translational velocity to the tangential velocity.

因为要找到它总速度，我们添加 渡速度到切向速度。

So, like linear velocity, tangential acceleration depends on the distance between the point and the center of the object.

因此，与线速度一样，切向加速度取决于点与物体中心之间距离。

And we know that in general, the magnitude of tangential velocity is also equal to the radius, times the angular velocity.

而我们知道，一般情况下，切向速度大小也等于半径乘以角速度。

Because at the bottom of the wheel, the tangential velocity is pointing opposite to the direction the wheel is rolling in.

因为在轮子底部，切向速度表示 反转车轮运向。

But there’s also tangential acceleration, which describes whether an individual point on a rotating object is speeding up or slowing down.

但也有切向加速度，它描述了旋转物体上单个点是在加速还是在减速。

Cal's ballpark suggestion here is to have at least two sources for each main point in your thesis, and at least one for any tangential or non-crucial points.

卡尔大致建议是，在论文中，每个主要观点至少要有两个支撑，且任何切题或非关键观点至少有一个支撑。

So, at any given moment, each of those points will have a tangential velocity that depends on the path it moves through -- specifically, the radius of that path.

因此，在任何给定时刻， 这些点中每一个都会有一个切向速度，该切向速度取决于它移经路径——具体来说， 就是该路径半径。

But the bottom of the wheel won’t be moving at all … because its total velocity is its translational velocity minus the tangential, since they’re moving in opposite directions.

但是轮子底部根本不会移… … 因为它总速度是它平移速度减去切向速度， 因为它们在相反向上移。

The previous dating of the africanus and prometheus fossils at Sterkfontein and other sites in South Africa led to them being regarded as tangential to the main, east African story of human evolution.

之前在斯泰克丹和南非其他地点发现非洲人和普罗米修斯化石年代，导致它们被认为与人类进化主要东非故事无关。

But we can also describe an object’s rotation in terms of its tangential velocity. This is the same type of velocity we used when we talked about the physics of uniform circular motion.

但我们也可以根据物体切向速度来描述物体旋转。这与我们在讨论匀速圆周运物理学时使用速度类型相同。

So Sarah, there's one thing we haven't talked about here, which is slightly tangential, but it's the office-spouse friendship, which is something that I'm obsessed with. Have you ever had an office spouse?

所以莎拉，有一件事我们在这里没有谈，有点离题，但这是办公室配偶友谊，这是我很着迷事情。有办公室配偶吗？

And we can only see that we've been following this year, how much those companies have grown, how the stock prices of NVIDIA, NVIDIA, and any other firm even tangential to AI is continuing to surge.

我们只能看到，我们今年一直在关注这些公司增长了多少，英伟达、英伟达以及其他任何与人工智能无关公司股价如何持续飙升。

Consequently,   none of Shakespeare's letters that he might have written during his lifetime have survived and we  are left reliant on extracting impressions about who he actually was on a personal level from  his plays, poems and other tangential sources.

因此，莎士比亚生前可能写下所有信件都没有保存下来，我们只能从他戏剧、诗歌和其他无关资料中提取关于他个人真实印象。
