当我们考虑到重力时，物体受重力，加速度影响，重力加速度，是一个常数。

When we have gravity an object is influenced by the gravitational acceleration and the gravitational acceleration is a constant.

说得具体些，相对论预言，时间并不是按照一个固定频率流动的，它会受到加速度的影响。

Specifically, Einstein's special theory of relativity predicts that time does not flow at a steady rate, and it can be affected by acceleration.

这个张力在不断增大，又因物体，无加速度-，物体受到向下的力影响-，张力必然不断增加？

So this tension goes up and up and therefore, since this object - is not being accelerated — - we're going to get a force down now on this object — this tension must increase, right?

youdao

But there are effects of the Earth's acceleration, which we'll demonstrate.

但地球的加速度还是会产生影响,这一点我们马上就要证明
