宇航员是怎么能承受10个重力加速,并且还是在不停转动方向的情况下的呢?,这难倒我了。
How these astronauts can do it at 10 g and the direction changing all the time, it beats me.
既然重力是恒定的,我施加的力在大小上,不变,就是方向不同,无所谓我怎么移动;,答案总是,相同的。
Since gravity is a conservative force, and since my force is always the same in magnitude except in opposite direction, ; it doesn't matter how I move in; it will always come up with the same answer.
重力势能,这样增长,重力;,是在这个方向,当我在这里。
When I'm here, gravitational potential energy ; increases in this way; the gravitational force is in this direction.
我还是问你,你感觉重力是什么方向的?
我再问你,你感觉到重力的方向是怎样的?
So now I ask you "Ah, in what direction do you perceive gravity?"
也许我的确疯了,但你会告诉我,重力是这个方向的。
You're right in that case, but nevertheless you say "Gravity is in this direction."
如果观察这些点,比如这个,那么那个,当然是等于重力,如果那里有个物体,在y方向。
So if we visit those points, for instance here, then there is, mg of course, gravity, mg, if there is an object there in the y direction...
我问你,你感觉到重力是哪个方向。
And so I say to you, "In what direction do you perceive gravity?"
你在这里的话,我先问你们,重力是什么方向的?
When you were standing here and I first ask you "in what direction is gravity?"
好我再问你,你感觉到重力是什么方向
Okay, so now I say to you "In what direction do you perceive gravity?"
所以就会产生向心加速度,在这个方向上,这些微粒会说,“啊哈,重力是这个方向的。”
Therefore, there is now a centripetal acceleration in this direction, and so the particles now say "Aha! Gravity is in this direction."
在缺少重力和方向精确度的情况下应该尽可能的去遵守就可以了.神不会让一个人去做超过他/她能力的事情的."
