an aircraft in steady flight over the earth is just as suitable an inertial frame of reference as the earth itself.
把固定的恒星说成是标準的非加速参照系,这是一种已经确立的习惯。
and therefore, in spite of these accelerations we will accept this hall as a reasonably good inertial frame of reference in which the first law then should hold.
所以,几乎可以忽略不计,教室是一个,很好的惯性参考系,第一定律在这儿是成立的。
and an inertial frame of reference would then be a frame in which there are no accelerations of any kind is that possible?
惯性参考系也就是不存在任何,形式加速度的参考系,有可能吗?
