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

我们以各种不同方式，不同方向，不同速度，动。

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、过度体力活动与强烈动均可导致椎盘突出，即椎盘从某一方向突出。

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

你知道？ 这就像这个球官方动。

Temperature is an average measure of how fast the molecules are moving, rotating, and vibrating.

温度是衡量分子动、和振动速度平均值。

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

相反，它们会打滑， 方向与动方向不符。

Because of their circular movement, these windstorms are also known as " twisters."

由于它们动， 这些风暴也被称为“涡” 。

Now it is important that we understand the difference between translational and rotational motion.

现在重要是我们要理解平移动和动区别。

And now we are just getting that rotational motion.

而现在我们只是得到了那种动。

" Whirl" describes a fast movement around and around.

" Whirl" 描述是快速动。

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

动在每个芽早期生长后停止。

They're great because we can start to tap into the rotary planes.

它们很棒，因为我们可以开始激活平面动。

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

动时，呼啦圈在身体周围。这种动和波利尼西亚人本土舞蹈——草裙舞类似。

In order to measure rotational motion.

为了测量动。

Now in rotational motion the equation looks a little bit different.

现在在动中，方程看起来有点不同。

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物体绕其自身轴动。

And this only works in rotational motion.

而这只有在动中才有效。

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

下一次，我们将看到动逻辑如何应用于另一个想法：动量！

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

但是当物体时，它一些动能 它采取动形式。

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

他们可以指定门、橱柜、时钟、动自行车。

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

但是动物理学与平移动物理学并没有什么不同。
