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。

Gravity is the attractive force between two objects with mass— any two objects with mass.

重是两个有质量物体之间吸— —任何两个有质量物体。

The molecules bind because of Van der Waals forces, the weak attractive force between uncharged molecules.

分子结合是因为范德华， 即不带电分子之间弱吸。

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，并受吸。

So, it generates a huge attractive force.

所以，它产生了巨大吸。

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。

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，如果你增加碳数量，你就会增加能存在吸数量。

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，物理学四种基本之一是强核，这是一种作用在原子核中质子和中子之间吸。

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。

In this case, the ball is in Earth's gravitational field, and so it feels an attractive force towards the Earth and the ball falls to the ground.

在这种情况下，球处于地球场中，因此它感受了朝向地球吸，并且球落了地面上。

You can walk on solid ground like dirt, wood, or concrete because the attractive forces between the molecules are strong enough to hold all of them in place.

你以在泥土、木头或混凝土等坚固地面上行走， 因为分子之间吸足以将它们固定在适当位置。

As the human meteoroid approached the sun or centre of attractive force, the attraction of one century squared itself to give the measure of attraction in the next.

当人类流星体接近太阳或吸中心时， 一个世纪吸将自身平方以得出下一个世纪吸。

So in order to have the sock and the shirt attracted to each other they must have opposite net charges because they're experiencing an attractive electric force.

因此，为了使袜子和衬衫相互吸，它们必须具有相反净电荷，因为它们正在经历吸电。

Motion is the ultimate object of science, and measures of motion are many; but with thought as with matter, the true measure is mass in its astronomic sense — the sum or difference of attractive forces.

运动是科学最终对象，运动量度有很多种；但是思想和物质一样，真正衡量标准是天文学意义上质量——吸总和或差异。

When a voltage is applied across two beamlike electrodes made of aluminium, which are separated by a gap of around 50 nanometres, charge builds up on each, creating an attractive force between them, until a critical point is reached.

两个柱状铝电极间隔约50纳米，当电压加在这两个电极之间时，它们就会相互通电，在二者之间会形成一股，直至达一个临界点。

Man commonly begs the question again taking for granted that he captures the forces. A dynamic theory, assigning attractive force to opposing bodies in proportion to the law of mass, takes for granted that the forces of nature capture man.

人们通常会再次回避这个问题，认为他获得了是理所当然。一种动学理论，根据质量定律将吸分配给相对物体，理所当然地认为自然会吸人。
