When the mass making the depression moves, that sends out ripples in space-time.

当该物体发生运动时，便在时空中产生了“涟漪”。

Or how does it affect of the state of an object?

或者说 合力是如何影响物体运动状态？

So radar gives you the direction of travel and measures the agent's movement within centimeters per second.

雷达告诉你方向，还测量物体运动精确到厘米每秒范围。

That's a lot like regular momentum, when an object in motion tends to stay in motion.

这与普通动量一样，当一个物体处于运动中时它倾向于保持这种运动。

There's no doubt that Einstein was right in setting that limit for objects moving through space.

无疑问，爱因斯坦为在太空中运动物体设定这个极限是正确。

The theory of relativity relates to the laws of gravity and describes the movement of large objects.

相对论与万有引力定律有关，描述了大型物体运动。

Time stops altogether on reaching the 299,792,458 metres per second at which light zaps through a vacuum.

当物体运动速度达到299792458米每秒时，即达到光在真空中传播速度时，时间整体停止。

But this inward force of gravity is

这个内向重力是 当物体运动时，将物体向内加速（沿重力方向）。

By every single movement. So it's a good thing that we can focus. However, we also need to remember.

所有物体运动都会让我们分心 所以我们能集中注意力是件好事 但是 我们也要记得。

If you time the movement of the object to be exactly during a saccade, people have a hard time noticing.

如果精确计算扫视过程中物体运动时间话，们很难注意到。

Things can travel faster than the speed of light, right here on Earth, and when that happens, it looks like this.

就在地球上，物体运动速度可以超过光速，当这种情况发生时，它看起来像这样。

Our present ideas about the motion of bodies date back to Galileo and Newton.

我们目前关于物体运动想法可以追溯到伽利略和牛顿。

And it's my job to study and predict motion of objects in space.

我工作是研究和预测空间物体运动。

OK, like Isaac Newton - an object in motion tends to stay in motion?

好吧，就像艾萨克·牛顿一样——运动中物体往往会保持运动状态？

An object in motion will stay in motion.

运动中物体将保持运动。

And second, rotating objects have angular velocity, just as translating objects have linear velocity.

其次，旋转物体具有角速度， 运动物体具有线速度。

443. Speed is defined as how quickly an object moves.

速度是指物体运动有多快。

When something is in motion, its position changes.

当物体运动时，它位置会发生变化。

In summary, kinetic energy is the motion energy of an object.

总而言之，动能就是物体运动能量。

He discovered the force of gravity. and he drew up the system of how objects move.

他发现了万有引力。他制定了物体运动系统。
