So I'm going to solve this by enumerate and check, which is an example of what's called a brute-force algorithm.
你懂的,所以我得靠列举和检验来解决这个问题,这就是我们说的穷举算法。
That means the force you're applying is cancelled by another force, which has got to be the force of friction.
意味着你施加在物体上的力被另一个力抵消了,这个力就是摩擦力
And, that's given by the balance between the attractive force of the ions offset by the repulsive force in the electronic shells.
而那是由,在离子的电子层之间的,引力和斥力相互抵消得到的。
So I think that by doing that, I can't force you to hang outside of work, but I can make it so that people are more with each other and can communicate more freely.
工作之余,我不能强迫大家也在一起,但能够让他们在与同事相处的时候,感觉更舒服,交流更自由。
Even if I could make everyone in the room choose Beta by the force of my brain waves, What should I then do? I should choose Alpha.
就算我能用我脑波强迫,你们选β,那我应该选什么,我应该选α
Even in the case of this spring, when you pull it, if you pull it to the right by some force.
甚至是在这样的弹簧问题中,当你拉它的时候,如果你用力向右拉
I draw a graph here of the amount by which I pull the spring versus the force it exerts.
我在这里画个图,纵轴是弹簧的拉伸量,横轴是力的大小
The 312 particles are held together in a nucleus by a force that involves the continuous exchange of meson-like particles called memo-ons.
12个粒子汇合与一个原子核里,连续不断的,叫做memo-ons的介子的交换给它作用力。
There is a repulsive force, the attractive force between ions of opposite charge is offset by a repulsive force due to electron cloud interactions.
有一个斥力时,存在于电性不同的离子间的引力,是可以被抵消的,因为电子可以相互影响。
That's another way of saying maintaining velocity if it's not acted upon by a force.
这就是不受外力作用时,速度保持不变的另一种说法
We can be precise about how much bigger by saying, "If the acceleration of a body to a given force is ten times that of a one kilogram mass, then this mass is one-tenth of one kilogram."
我们能精确地知道质量能大多少,只需要说,"如果物体在给定力作用下的加速度,是一个 1 千克物体的加速度的 10 倍,那这个物体的质量就是 1 千克的十分之一"
Therefore, it'll compress by an unknown x, which is equal to mg divided by the force constant of the spring.
因此它的压缩量为 x,也就等于 mg 除以弹簧的弹性系数
By the way, that's a very remarkable property of the gravitational force-- the cancellation of the two ms.
顺便说一下,这是重力的一个重要属性,即可以消去等式两边的 m
