We also described how the position of an object in simple harmonic motion changes over time.

我们还研究了如何改变对象的位置 它具有随时间的简谐运动。

Meanwhile, Galileo focused on Earth's surface, studying simple motion phenomena such as balls rolling down slopes and pendulums swinging.

与此同时，伽利略专注于地球表面，研究简单的运动现象，例如球从斜坡上滚下和钟摆摆动。

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。

So now, with the help of our knowledge about circular motion, we can understand the period, frequency, and angular velocity of the ball’s simple harmonic motion as it oscillates on the spring.

所以现在， 借助我们关于圆周运动的知识，我们可以了解球在弹簧上振荡时的简谐运动的周期、频率和角速度。

This is the responsibility of higher-level robot software, which plans and executes robot actions, like plotting a path around sensed obstacles or breaking down physical tasks, like picking up a ball, into simple, sequential motions.

这是更高层软件的责任软件负责做出计划，并让机器人执行动作，比如制定一条路线来绕过障碍物，或者把任务分成一步步，比如把拿起一个球，分解成一个个简单连续动作。
