In Switzerland, a small school of zebrafish swim around a circular path, with a camera overhead tracking their position.

在瑞士，一小群斑马鱼绕着圆形路径游动，头顶上的摄像头跟踪它们的位置。

The planets are shown to revolve in a nice circular path, forming concentric rings, with the sun sitting smack dab in the center.

这些行星以一个漂亮的圆形轨道公转，形成同心圆环而太阳恰好位于中心。

The shape of the circular path itself makes circle A do an additional rotation to return to its starting point.

圆形路径本身的形状使圆 A 进行额外的旋转以返回其起点。

In this case, as the wave travels to the right, the water molecules themselves basically move along circular paths.

在这种情况下， 当波向右传播时，水分子本身基本上沿着圆形路径移动。

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 当物体在圆形路径上匀速运动时。

To an external observer, they'll see the earth do one extra rotation to account for its circular path around the sun.

对于外部观察者来说，他们会看到地球额外旋转一周，以解释其绕太阳的圆形路径。

The planetary model taught in school, consisting of planets following circular paths, naturally stacks one planet above the other without crossing the path of each other.

学校教授的行星模型由遵循圆形路径的行星组成，自然地将一颗行星堆叠在另一颗行星之上，而不会相互交叉。

For a long time, from Ptolemy to the age of Copernicus, it was widely believed and accepted that planets revolved in a perfectly circular path.

在很长一段时间里，从托勒密到哥白尼时代，人们普遍相信并接受行星以完美的圆形轨道运行。

A rock thrown hard enough sideways will fall toward the Earth, but always miss it, going instead into a circular path around it, guided only by gravity.

一块被用力抛出的石头总是在朝向地球坠落，并且总是错过地面，于是它就只由引力引导，在一个环形轨道上运动。

Find the ratio between the circumferences of circle B and circle A and then add one rotation to account for the circular path traveled.

求出圆 B 和圆 A 的周长之比，然后加上一圈旋转来计算所经过的圆形路径。

While this vision of planets following a nice circular path around the Sun looks neat and tidy for a school project, in reality, things aren't that simple.

虽然这幅行星沿着一个漂亮的圆形轨道围绕太阳运行的景象对于老师教学来说很整洁，但事情并没有那么简单。

For one thing, the ball on the spring is moving in one dimension, while a marble moving along a circular path is in two dimensions.

一方面， 弹簧上的球是一维运动的，而沿圆形路径运动的弹珠是二维运动的。

And, when you think about it, any rigid object rotating around a fixed axis is basically a set of points, all moving along circular paths.

而且，仔细想想，任何围绕固定轴旋转的刚性物体基本上都是一组点，它们都沿着圆形路径移动。

It's only as external observers that we actually see the outer circle travel a circular path back to its starting point, giving us the one extra rotation.

只有当外部观察者看到外圈沿着一条圆形路径回到它的起点时，我们才会多转一圈。

In those cases, we described how, when an object moves along a circular path, its velocity is perpendicular to the radius of the circle, in the direction of the motion.

在那些情况下，我们描述了当物体沿圆形路径移动时，其速度如何在运动方向上垂直于圆的半径。
