If every time I get the same acceleration, I'm convinced this is a reliable spring that is somehow producing the same force under the same condition.
如果每次都能得到相同的加速度,这个弹簧的可靠性就能令人信服,即它在相同的条件下能够产生相等的力
So springs are always pushed or pulled on either side with the same force.
所以弹簧两边永远都是受到,相同的压力或拉力
It turns out in the world of classical music there's a stereotype of women being simply less proficient than men: they play smaller than men, they don't have the same force and they have smaller techniques, they're more temperamental and so on.
在古典音乐界,有一个刻板印象,女人的造诣就是不如男人:,她们演奏得不如男人宏大,她们力量不如男人,她们技巧不如男人,她们喜怒无常等等。
How do you deal with that trade-off where you absolutely need an ad sales force but at the same time, if one person at a time, you just can't say let's go out and hire five good engineers or five good ad sales people and not have them be great?
如何做出选择,如何取舍,当你急需一批销售人员,但如果只碰见一个合适的人选,你不只能因此去找,5个差不多的工程师,或者5个差不多的广告销售?
So the real pressure is not quite the same because of this attractive force as it was, as it would be without the attractive forces.
气体压强,由于分子间的吸引作用,会比理想气体要小,这样,我们应该修正p的值。
Remember, the wall is pulling to the left with the same force.
记住这个墙也要向左用相同的力拉它
The force is not known, but it's the same force.
力的大小未知,但与前一个力大小相等
For example, how do I know that when I pull the spring the first time for the mass, it exerted the same force when I pulled the spring the second time for the elephant?
例如 怎样才能知道,第一次连着物体拉弹簧时,产生的力和,第二次连着大象拉弹簧时产生的力是相等的呢
