first law of motion

基本解释

I'm pretty sure that Sir Isaac would have loved to see this, as it would have proved his first law of motion to be correct.
我相信伊萨克·牛顿爵士也很想见到这一切，因为这能证明他的第一运动定律的正确性。

Then somehow he hinted the Second Law of Thermodynamics and the Perpetual Motion Machine (of the First Kind… Haha)… then I explained the negative sign… then I don't owe him any assignment… lol.
然后后来不知道为什么他就提示了热力学第二定律和第一类永动机…然后我就解释了…然后现在他就欠我作业了…哈哈哈…

The Laws of Planetary Motion Kepler's First Law: The orbits of the planets are ellipses, with the Sun at one focus of the ellipse.
行星沿椭圆轨道绕太阳运行，太阳位于椭圆的一个焦点上。对任一个行星说，它的径矢在相等的时间内扫过相等的面积。

It seems that Sir Isaac Newton got it right with his First Law of Motion: Bodies at rest tend to stay at rest.
