速度与

The rate at which the flowing water overcomes this resistance is related to the permeability of rocks.

水流克服这种阻力的速度与岩石的渗透性有关。

Do not confuse ever the tangential acceleration, which is along the circumference, with centripetal acceleration.

不要把沿圆周的切向加速度与向心加速度混淆。

Although no form of matter yet discovered, moves as fast as or faster than light, scientific experiments have already confirmed that accelerated motion causes a traveler´s time to be stretched.

虽然还没有发现一种速度与光一样或比光还快的物质，但科学实验已经证实，加速运动会延长旅行者的时间。

Enums - speed vs. readability in the database.

枚举——数据库中速度与可读性的较量。

So, that means the acceleration is parallel to the position.

这意味着加速度与位矢平行。
