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

或者说 合力是如何影响体动状态的？

But this inward force of gravity is

这个内向重力是 当体动时，将体向内加速（沿重力方向）。

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

毫无疑问，爱因斯坦为在太空中动的体设定的这个极限是正确的。

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

次，旋转体具有角速度， 动体具有线速度。

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

当该体发生动时，便在时空中产生了“涟漪”。

An object in motion will stay in motion.

动中的体将保持动。

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，描述了大型体的动。

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

当体动速度达到299792458米每秒时，即达到光在真空中的传播速度时，时间整体停止。

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

雷达告诉你行驶的方向，还测量体的动精确到厘米每秒的范围。

Because motion devices are unfamiliar to the blind, the task I gave them involved some problem solving.

由于盲人并不熟悉动体，所以我给他们的任务中包含了一些解决问题的内容。

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

这与普通的动量一样，当一个体处于动中时它倾向于保持这种动。

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

速度是指体动的有多快。

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

总而言之，动能就是体动的能量。

An object moving as fast as possible, at the speed of light, no longer moves through time.

以光速尽可能快地动的体不再随时间动。

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

我们目前关于体动的想法可以追溯到伽利略和牛顿。

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

所有体动都会让我们分心 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体动时间的话，人们很难注意到。

When something is in motion, its position changes.

当体动时，它的位置会发生变化。

This effect is only really significant for objects moving at speeds close to the speed of light.

这种效果仅对以接近光速的速度动的体才真正有意义。

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

我的工作是研究和预测空间体的动。
