Gravity is an attractive force between any two masses.

重力是任何两个物体之引力。

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

同时还有水分子之将水滴保持在一起吸引力。

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引性分子力。

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

一般来说，我们可以将重力定义为将两个物体拉在一起吸引力。

So, it generates a huge attractive force.

所以，它产生了巨大吸引力。

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

如果我们拥有相反电荷，就会产生吸引力。

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

较弱分子力意味着，你只需投入更多能量，就能更容易地克服这些吸引力。

But London dispersion forces are going to be attractive forces.

但伦敦分散力量将成为吸引力力量。

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

在上一个视频中，我向您展示了引力是如何为所有物质之一种吸引力存在。

There will be an attractive force between the two.

两者之会产生吸引力。

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

重力是一种吸引力，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引力数量。

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

然后我们会得到红绿之吸引力。

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

因此，球处于地球引力场中，并受到引力吸引。

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

所以这里有一个吸引力，存在于带电气球和原本是中性墙壁之。

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

我们说它们是吸引力，它们存在于所有有质量物体之。

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水强大表面张力，即液体分子之吸引力。

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，物理中四种基本力之一是强力，这是一种于原子核内质子和中子之吸引力。

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引力吸引力引起。

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力，表面张力是由水表面水分子之化键形成吸引力。
