It was turning into a battle between the second law of thermodynamics and Newton's law of universal gravitation.

它变成了热力学第二定律和牛顿万有引力定律之间的斗争。

Newton wasn't working in the orchard when the apple hit him and he discovered the law of universal gravitation.

当苹果砸到牛顿时，他没有在果园里工作，他发现了万有引力定律。

Newton's law of universal gravitation, which had stood uncontested for over two centuries, depicted gravity as a force acting between two bodies.

牛顿的万有引力定律在两个多世纪以来一直没有受到争议，它将引力描述为作用在两个物体之间的力。

Newton’s law of universal gravitation is incredibly useful.

牛顿万有引力定律非常有用。

He formulated what we call the Law of Universal Gravitation.

他制定了我们所说的万有引力定律。

Newton had enough to establish his law of universal gravitation.

牛顿已经足够建立 吸引力法则。

Newton's law of universal gravitation is incredibly useful.

牛顿吸引力法则。

Today, you learned about how Newton came up with his law of universal gravitation.

今天你学会了如何发现 牛顿的万有引力定律。

Scientists’ understanding of gravity has evolved since then, but Newton’s Law of Universal Gravitation is still a good approximation in most situations.

从那时起，科学家们对引力的理解发生了变化，但牛顿万有引力定律在大多数情况下仍然是一个很好的近似。

But even though he didn’t know the exact value of big G at the time, Newton had enough to establish his law of universal gravitation.

但即使当时他不知道大 G 的确切值，牛顿也足以建立他的万有引力定律。

In an ironically similar string of events, Isaac Newton proposed what is known as the law of universal gravitation in his same work that argued for absolute time.

在一连串具有讽刺意味的类似事件中，艾萨克·牛顿（Isaac Newton）在他论证绝对时间的同一著作中提出了所谓的万有引力定律。

The authenticity of this story cannot be verified and in fact, it was Kepler's three laws that truly motivated the formulation of the law of universal gravitation.

这个故事的真实性无法证实，事实上，真正推动万有引力定律制定的是开普勒三定律。

Well, from Newton’s law of universal gravitation, we know that the acceleration of stuff at Mars’s surface would be equal to big G, times the mass of Mars, divided by Mars’s radius squared.

好吧，根据牛顿万有引力定律，我们知道火星表面物质的加速度等于大 G 乘以火星质量，再除以火星半径的平方。

There’s one more thing we should point out about Newton’s law of universal gravitation, which is that it fits what we expect the equation for a net force should look like, according to Newton.

关于牛顿万有引力定律， 我们还应该指出一件事，根据牛顿的说法， 它符合我们期望的合力方程式。
