inertial reference frame

基本解釋

Well, the First Law works when the frame of reference is what we call an "inertial" frame of reference.
牛頓第一定律只有當,當參考系為慣性參考系時成立。
And an inertial frame of reference would then be a frame in which there are no accelerations of any kind Is that possible?
慣性參考系也就是不存在任何,形式加速度的參考系,有可能嗎？
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，幾乎可以忽略不計,教室是一個,很好的慣性參考系,第一定律在這兒是成立的。

So the Earth is an inertial frame of reference, if you go in a train relative to the Earth at constant velocity, you're also inertial.
所以,地球是一個慣性參考系,如果你坐在相對于地球勻速運動的火車里,你也處于慣性狀態(tài)
