今天我们将讨论，我们所说的“匀速圆周运动。”

Today we will discuss what we call "uniform circular motion."

youdao

谓围绕着作圆周运动；转动。

Students round the circular movement; turn.

youdao

从匀速圆周运动来看。

Remember, from the uniform circular motion.

youdao

在他之前，人们认为，它们不是做圆周运动。

Before him, people were saying, well, they cannot move in a circle.

youdao

否则无法做圆周运动。

Otherwise, you could never do this.

youdao

质量是小m的,物体围绕着,大M作圆周运动。

There's an object mass little m going in a circle around capital M.

youdao

这个过程不是一个圆周运动而是螺旋上升型的。

The process is not a circle but rather a spiral.

youdao

头部放松向前倾，下巴顶着胸骨，头部做圆周运动。

Release your head forward, chin resting against the sternum. Make circles with your head.
