解答几道英文版的关于时空、相对论的物理题,英语及物理界的高手来,
1.Can you travel while remaining in one place in space?Explain.
2.Does light travel through space?Through time?Through both space and time?
3.What does it mean to say that motion is relative?
4.The speed of a ball you catch that is thrown from a moving truck depends on the speed and direction of the truck.Does the speed of light caught from a moving source similarly depend on the speed and direction of the source?Explain.
5.What does it mean to say that the speed of light is a constant?
6.The ratio of velocity gain to time for a freely falling body is g.Similarly,what is the ratio of distance to time for light waves?

1.你能在静止时旅行吗?(可以的,因为物体的运动是相对的,这和参照物的选择有很大关系。其实你背个包旅行时,就是相对于包在做静止旅行。)
2.光是在空间中穿过,还是在时间中穿过,还是两者皆有?(光速可以超越时间,爱因不是说过,当一物体速度比光速快时,时光可以倒流。可以说光即是在空间中穿过,又在时间中穿过。)
3.运动是相对的意思??(意思就是说不绝对,这和参照物有很大关系。)
4.你接住一个从行驶中的卡车上扔下来的球时,球的加速度方向取决于卡车行驶的方向,从一个运动中的光源发出的光的速度是否也取决于光源的速度与方向。(可以说从方向上可以取决于光源,由于光的速度很快,至于加速度可以不用考虑,但说速度取决于光源也不算错)
5.光速是恒定的含义??(在不同的参考系中光速保持大约300000km/s)
6.*落体和加速度的比值同样的道理,光波的长度和时间比是多少?(这个是不能确定的。波长越长,时间短,频率就大。波长越短,时间长,频率就小。)

高悬赏。。。文科生默默爬过
better google & wiki them

第一题,能在保持静止的情况下旅行吗?我觉得可以,因为运动是相对的,你在这个参考系下静止,在其他的参考系中可能是运动的.第二题,光传播经过时间、空间吗?是的,应该既经过时间也经过空间.3.运动是相对的是什么意思.也...

翻译还是解答?这些题目现在能看懂不会解答,十年前看不懂但能解答。
我给你翻一下,答案不是很确定了。你发到物理学科类别下面去问问看。
1.Can you travel while remaining in one place in space? Explain.
你可以在同一地点运动么?请解释。(我想这题考的是参照物,初一学过的。相对于运动中的物体,你是静止的)
2.Does light travel through space? Through time? Through both space and time?
光是在空间中运动还是在时间中运动?抑或是在时空中运动? (光速运动可以超越时间,光本来就是在空间运动的)
3.What does it mean to say that motion is relative?
为何运动是相对的? (参照物的关系)
4.The speed of a ball you catch that is thrown from a moving truck depends on the speed and direction of the truck. Does the speed of light caught from a moving source similarly depend on the speed and direction of the source? Explain.
当你接住一个从行驶中的卡车上扔下来的球时,球的速度取决于卡车的速度与方向。从一个运动中的光源发出的光的速度是否也取决于光源的速度与方向?请解释。 (光速那么快,光源的速度和方向的加成直接忽略不计了。)
5.What does it mean to say that the speed of light is a constant?
光速是永恒的,这是什么意思? (光永远是那个速度,任何情况下都是。)
6. The ratio of velocity gain to time for a freely falling body is g. Similarly, what is the ratio of distance to time for light waves?这一题,汗!g是什么来着?我居然忘了。好像跟地球引力有关,数值是9.8。题目意思是,既然*落体的?与时间比是一个g,那么光的长度与时间之比是多少?
(光速?)
