One area where the conflict between quantum theory and relativity comes to the fore is in the gravitational constant, g, the quantity that describes the strength of gravity.

凸显量子理论和相对论冲突的地方之一是引力常数g，这个量描述引力的强度。

The planet – Gliese g – appears to have an atmosphere and gravity similar to that of Earth.

这颗行星—格里斯g—大气和重力与地球相似。

Now, gravity, well force, is equal to mass times acceleration, g and the acceleration due to gravity is g.

是重力，等于质量乘以加速度，由重力导致的加速度是。

You can see that if a was equal to g, your downward acceleration is that of gravity, namely the cable has snapped in the elevator, Then you don't feel any weight.

你会发现如果 a 等于 g,你下降的加速度就是重力加速度,也就是电梯的绳索断了,那时你会完全失重

For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.

例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
