我们怎样才能测量出弹簧常数呢？

How can we measure the spring constant?

youdao

因此弹簧，一直可以用来测量，哦，一个物体，不管重力是多少。

So a spring always allows you to measure, uh, a mass even in the absence of gravity.

所以你可以,在飞船里用弹簧测量,物体质量，让它振荡,如果你知道弹簧常数，这也是实际操作中,所用的方法。

So you can actually measure the mass of an object using a spring on the shuttle and let it oscillate if you know the spring constant, and that's the way it's actually done.

Now I can measure that, because I pull it by one centimeter and I find the acceleration it exerts on a known mass.

现在就能测量这个力了,因为把弹簧拉伸 1 厘米,我就知道它让一个质量已知的物体产生的加速度

This is how masses can be tabulated using a spring.

这就是为什么能用弹簧测量物体质量
