We also talked about angular acceleration, as well as constant angular acceleration.

我们还谈到了角加速度， 以及关于均匀角加速度。

It's saying that constant acceleration is equal to the change in velocity divided by the change in time

表明恒加速度为 速度的变化除以时间的变化。

So Einstein realized that this meant that if the equivalence principle is correct, then light would bend due to gravity in exactly the same way that it would bend due to constant acceleration.

所以爱因斯坦意识到，如果等效原理是正确的，那么光会以完全相同的方式受到重力的弯曲。
