Gravity is an attractive force between any two masses.

重是任何两个物体之间。

And there's attractive forces between the water molecules holding the drop together.

同时还有水分子之间将水滴保持在一起吸。

Remember as a gas gets closer to condensation we're going to have more of these attractive intermolecular forces.

请记住, 当气体接近凝结时, 我们将拥有更多这些吸性分子间。

In general, we can define gravity as an attractive force that pulls two bodies together.

一般来说，我们可以将重定义为将两个物体拉在一起吸。

So, it generates a huge attractive force.

所以，它产生了巨大吸。

If we have opposite charges there is going to be an attractive force.

如果我们拥有相反电荷，就会产生吸。

Weaker intermolecular forces, you put more energy in and they're easier to overcome those attractive forces.

较弱分子间作用意味着，你只需投入更多能量，就能更容易地克服这些吸。

But London dispersion forces are going to be attractive forces.

但伦敦分散量将成为吸量。

Now in the last video I showed you how gravity is this attractive force between all matter.

在上一个视频中，我向您展示了是如何作为所有物质之间一种吸存在。

There will be an attractive force between the two.

两者之间会产生吸。

Gravity is an attractive force, so objects with mass want to move towards the surface of the Earth.

重是一种吸，因此具有质量物体想要向地球表面移动。

Now, if you increase the number of carbons, you're going to increase the number of attractive forces that are possible.

现在，如果你增加碳原子数量，你就增加了可能存在吸数量。

And then we would have the attractive force between the red and the green.

然后我们会得到红绿之间吸。

And so the ball is in the field of gravity for Earth and experiences an attractive gravitational force.

因此，球处于地球场中，并受到吸。

So we have an attractive force here between charged balloon and what used to be a neutral wall.

所以这里有一个吸，存在于带电气球和原本是中性墙壁之间。

We said they are attractive forces, and that they exist between all objects with mass.

我们说它们是吸，它们存在于所有有质量物体之间。

For really tiny animals, all they need to do is take advantage of water's strong surface tension, an attractive force between molecules on a liquid.

对于非常小动物来说， 它们所需要做就是利用水强大表面张，即液体分子之间吸。

Well, one of the four fundamental forces of physics is the strong nuclear force, an attractive force that acts between protons and neutrons in a nucleus.

好吧，物理学中四种基本之一是强，这是一种作用于原子核内质子和中子之间吸。

Compounding the error, Galileo mocked a proposal made by others, including Kepler, according to which the tides are caused by the attractive force of the moon.

更糟糕是，伽利略嘲笑了一个由其他人（包括开普勒）提出观点，该观点认为潮汐是由月球吸起。

If you have, then you have experienced the effect of surface tension, an attractive force created by chemical bonds between water molecules at a water's surface.

如果有，您就已经体验到了表面张作用，表面张是由水表面水分子之间化学键形成吸。
