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

我们不的方式，不的方向，不的速度，旋转运动。

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

不良的姿势、创伤、过度体力活动与强烈的旋转运动均可导致椎间盘突出，即椎间盘从某一方向突出。

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

旋转运动在每个芽的早期生长后停止。

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

但是旋转运动的理学与平移运动的理学并没有什么不。

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

但旋转运动也存在，而且很重要。

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的方程 旋转运动听起来很熟悉。

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

他们可指定旋转门、旋转橱柜、旋转时钟、旋转运动自行车。

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

但是对于旋转运动， 我们真的想知道体的角度——我们称之为 theta。

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

有时旋转运动可解释一些事情 这似乎不可能，但它是真实的。

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

你知道？ 这就像这个旋转球的官方运动。

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

扭矩基本上做样的事情， 但它特定于旋转运动。

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

下一次，我们将看到旋转运动的逻辑如何应用于另一个想法：动量！

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

传统上由僧侣演奏的十八个缅甸旋转铃是另一项运动的核心部分。

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.

我想花点时间来逆向旋转运动。加上肩部和颈部一起运动。

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

在体不旋转运动的情况下，所有这些 动能用于平移运动。

It's known as uniform circular motion, and it's what occurs when anything moves along a circular path in a consistent way.

它被称为匀速旋转运动 当体在圆形路径上匀速运动时。

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

它们相的方式影响旋转运动 质量影响平移运动。

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，它的一些动能 它采取旋转运动的形式。

This kept it spinning around your body. The motion was like one used by Polynesian people in their native dance, the hula.

运动时，呼啦圈在身体周围旋转。这运动和波利尼西亚人本土舞蹈——草裙舞类似。

Do I think all children have a relationship with movement? There's something about the children that catches the whirls -- W-H-I-R-L-S -- of motion that are happening.

我认为所有的孩子都和运动有关系，孩子们总能捕捉到正在发生的旋转运动。
