An object in motion stays in uniform motion unless acted upon by an external force.

除非受到外力作用，否则运动中的物体将保持匀速运动。

" Oh. Sorry." The man in the uniform motioned me forward with a flick of his stubby finger.

“哦对不起。 ” 穿制服的男人用粗短的手指轻轻一弹， 示意我向前。

Simple harmonic motion is actually a lot like uniform circular motion, mathematically speaking.

简谐运动其实就像 很多圆周运动，在数学意义上。

You might recognize those terms, because we’ve already talked about them in our episode on uniform circular motion.

您可能认得这些术语， 因为我们已经在匀速圆周运动一集中讨论过它们。

Eugenie drew her stitches with a uniform motion which revealed to an observer the teeming thoughts of her meditation.

尤金妮以匀速的动作画线，向观察者展示了她沉思的丰富思想。

This is the same type of velocity we used when we talked about the physics of uniform circular motion.

这与我们使用的速度相同 我们讨论了匀速圆周运动的物理学。

You might recognize those terms, because we've already talked about them in our episode on uniform circular motion.

您可能会认出这些术语，因为我们讨论过它们 已经处于匀速圆周运动循环中。

So, let’s recall what we know about uniform circular motion, to see what it can tell us about simple harmonic motion.

那么，让我们回顾一下我们对匀速圆周运动的了解， 看看它能告诉我们什么关于简谐运动。

So, let's recall what we know about uniform circular motion, to see what it can tell us about simple harmonic motion.

让我们回忆一下我们对匀速圆周运动的了解， 让我们看看它可能会告诉我们关于简谐运动的信息。

Now, we’ve also talked about the frequency of uniform circular motion: It’s the number of revolutions the marble makes around the ring every second, and it’s equal to 1, divided by the period.

现在，我们还谈到了匀速圆周运动的频率：它是弹珠每秒绕圆环转的圈数，等于 1 除以周期。

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的切向速度来描述物体的旋转。这与我们在讨论匀速圆周运动物理学时使用的速度类型相同。
