constant velocity

基本解釋

We did a demonstration there with two vibrating objects with a spring, but yet the center of mass was moving with a constant velocity.
我們做過演示的,彈簧連接兩個(gè)振動(dòng)物體，但是質(zhì)量重心,卻保持穩(wěn)定速度。
Setiawan and colleagues at Max Planck and the European Space Agency noticed that the star didn't move at a constant velocity relative to our sun.
塞蒂亞萬(wàn)和馬普學(xué)會(huì)的同事們以及歐洲航天局的同事們注意到：相對(duì)于我們的太陽(yáng)來說，恒星HIP 13044并沒有以恒定的速度移動(dòng)。

Then the center of mass, but only the center of mass, would have a velocity that never changes, because if there's no external force then there is only a constant velocity.
那么整體的中心，也僅僅是整體的中心，會(huì)有一個(gè)不變的速度，因?yàn)樗皇芡饬?它有一個(gè)持續(xù)的速度。

If I am an inertial observer, another person moving relative to me at constant velocity will also be an inertial observer.
如果我是慣性觀察者,那另一個(gè)相對(duì)于我做勻速運(yùn)動(dòng)的人,也是一個(gè)慣性觀察者

But things which were at rest will move at a constant velocity, opposite of the velocity that you have relative to me.
這些靜止的東西都在勻速運(yùn)動(dòng),方向正好跟你相對(duì)我運(yùn)動(dòng)的速度方向相反

The great discovery that Galileo and Newton made is that you don't need a force for a body to move at constant velocity.
伽利略和牛頓的偉大發(fā)現(xiàn)就是,物體不需要力來維持勻速運(yùn)動(dòng)
