They walk slower toward the elevator., then the people who were not primed with these old words, subconscious completely.
但他们走向电梯的速度,比没有受到影响的人慢,完全是潜意识的。
But ah... yes, there is a slight problem with the elevator.
但是,呃……对,电梯出了点问题。
Second, he looked at these people and measured how fast they walk from where their experiment was to the elevator.
第二,他观察这些人,记录他们从实验地点,走到电梯的时间。
I know some of you come from Europe and other parts of the world where the ground floor is rez-de-chauss?e or some silly thing like this 1 and you push a button on the elevator to one and you go up to the first floor.
我知道你们中间有些人来自欧洲,或者世界其他地方,你们那里的一楼,和地面齐平,或者像这样可笑的事情,比如你要按下电梯的按钮,然后才能上到真正的1楼。
First, take the case in the elevator is on the ground floor of some building and completely addressed.
首先我们来看看电梯,在一楼时候的情况
And then of course, the point of the skit is he presses the down button on the elevator and a minute and a half goes by while he's waiting for the elevator to come.
当然,这个滑稽短剧的笑点是,他按下了电梯按钮,花了一分半,等电梯。
There is a slight problem with the elevator.
电梯出了一点小故障。
Whether you take the elevator to the top of the Hancock Tower or whether you walk up the stairs, the change in gravitational potential is identical.
不管你是乘电梯,去大厦的顶层,或者是步行,重力势能的变化是相同的。
As you come to the top of the building, the elevator has to decelerate, so that it loses its positive velocity and comes to rest.
当你要到顶时,电梯需要减速,此时电梯速度减小最后静止
It means, when you are accelerating upwards, as the elevator picks up speed, the reading on the spring will be more and you will feel heavy.
也就是说当你向上做加速运动时,就像电梯加速的时候,弹簧的读数会增大,你会觉得自己变重了
When someone comes to us in the elevator in William James , ?" I says, "How are you doing?"
有人走向我们,在William,James大厅的电梯里,我说“你好吗“
Here is a weighing machine and that's you standing on the elevator.
这是个称重器,然后你在电梯里
In William James, maybe the case-- because the elevator-- it does take two hours to get there for the door to close.

And they walk significantly slower toward the elevator, not knowing that they were primed with old words.
走向电梯的速度明显慢,虽然不知道自己被与“老“相关的字影射过。
We all know that in a falling elevator, you definitely do not escape the pull of gravity.
我们都知道在一个下坠的电梯里,你当然还是会受到重力的
You can see that if a was equal to g, your downward acceleration is that of gravity, namely the cable has snapped in the elevator, Then you don't feel any weight.
你会发现如果 a 等于 g,你下降的加速度就是重力加速度,也就是电梯的绳索断了,那时你会完全失重
I'm going to give the last class a problem which is pretty interesting, which is what happens to you when you have an elevator.
我将讲解最后一个例题,非常有趣,也就是当你在电梯里的情形
Now, what happens if the elevator is accelerating upwards with an acceleration a?
现在如果电梯向上以加速度 a 运动,会发生什么呢
