We move in all kinds of different ways, different directions, different speeds, rotations.

我们以各种不同式，不同，不同速度，旋转运。

Poor posture, traumas, physical activity and strong rotation movements can cause herniation, where disc bulges out in one direction.

不良姿势、创伤、过度体力活与强烈旋转运均可导致椎间盘突出，即椎间盘从某一突出。

The revolving movement ceases after the early growth of each shoot.

旋转运在每个芽早期生长后停止。

In the case of objects that move without rotating, all of that kinetic energy goes into translational motion.

在体不旋转运情况下，所有这些 能用于平移运。

They can point out their " revolving door" , the " rotating cabinets" , the " turning" clocks, the " spinning" exercise bike.

他们可以指定旋转门、旋转橱柜、旋转时钟、旋转运自行车。

Scroll wheels commonly use either optical rotary  encoders or magnetic rotary position sensors in order to measure rotational motion.

滚轮通常使用光学旋转编码器或磁性旋转位置传感器来测量旋转运。

Next time, we’ll see how how the logic of rotational motion applies to another idea: momentum!

下一次，我们将看到旋转运逻辑如何应用于另一个想法：量！

Because, first, the moment of inertia affects rotational motion in the same way that mass affects translational motion.

它们以相同式影响旋转运 质量影响平移运。

But when an object is ROTATING, some of its kinetic energy is also taking the form of Rotational Motion.

但是当体旋转时，它一些能 它采取旋转运形式。

But the physics of rotational motion isn’t all that different from the physics of translational motion.

但是旋转运理学与平移运理学并没有什么不同。

But rotational motion is also a thing -- and an important one.

但旋转运也存在，而且很重要。

Torque essentially does the same thing, but for rotational motion.

扭矩基本上做同样事情， 但它特定于旋转运。

Now, other definitions of a revolution do include the motion of an object rotating about its own axis.

现在，革命其他定义确实包括体绕其自身轴旋转运。

You know? It's like the official sport of this spinning ball.

你知道？ 这就像这个旋转球官运。

Instead they could skid, rotating not in their direction of travel.

相反，它们会打滑， 旋转与运不符。

But for rotational motion, we really want to know the object’s angle -- what we call theta.

但是对于旋转运， 我们真想知道体角度——我们称之为 theta。

Eighteen Burmese spinning bells, traditionally played by monks, are a central part of another movement.

传统上由僧侣演奏十八个缅甸旋转铃是另一项运核心部分。

I want to make sure I take time to reverse my circle. Checking in with the elbows. I'm beginning to get the neck involved here.

我想花点时间来逆旋转运。加上肩部和颈部一起运。

And many of the equations you use to describe rotational motion will look really familiar to you.

还有很多我们将用来描述程 旋转运听起来很熟悉。

And, there are times when rotational motion can explain things that sound impossible, but actually are true.

有时旋转运可以解释一些事情 这似乎不可能，但它是真实。
