下面我将讨论,完全失重状态,记得几节课之前,我将你系在,绳子的末端。
I now want to return to the idea of complete weightlessness and I want to remind you, a few lectures ago how I was swinging you at the end of a string in the vertical.
绳子没有张力,完全松弛,不管吊着的是你还是水桶,均为失重状态。
So the string has no tension, the string goes limp and the bucket of water and you are weightless.
