Here I got 3 kg and I got 2 kg and I'm pushing with 10 Newtons and I want to know what happens.
一个物体 3 千克,另一个 2 千克,现在我用 10 牛的力推它,我想知道接下来会怎样
That is 6 Newtons divided by 3 kg is also an acceleration of 2.
即,6 牛除以 3 千克同样得到加速度是 2
And then I convert that to mass, and that gives me 24.7 kg of titanium.
换算成质量,就是24。7kg的钛。
I got 2 kg and I pull this guy with 10 Newtons.
还有一个 2 千克的物体,我用 10 牛的力来拉它
Newtons acting on 2 kg, gives you an acceleration of 2.
牛的力作用在 2 千克的物体上,那么其加速度大小就是 2
I got 3 kg and I have a rope.
有一个 3 千克的物体和一根绳子
If your plan is to accelerate a 3 kg mass with an acceleration of 2 meters per second, you better have a rope that can furnish that force and it can take the tension of 6 Newtons.
如果你想用 2 米每秒平方的加速度,去拉一个 3 千克的物体,那么你就需要一根能提供拉力的绳子,并且它能够承受 6 牛的张力
kg is being pulled by the rope on the right with a force that I'm going to call T, which stands for tension.
千克的物体受到绳子向右的一个拉力,我称它为 T,也就是拉力的意思
OK, so let's say some young engineer is on the job the first day and says, OK, let's put in 200 kg of tickle, and let's put in about 25 kg of mag.
比如一些年轻的工程师,刚来上班时会说,投入200kg的四氯化钛,投入25kg的镁。
