Gravity is an attractive force between any two masses.

是任何两个物体之间的引。

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

同时还有水分子之间水滴保持在一起的吸引。

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

一般来，我们可以定义为两个物体拉在一起的吸引。

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

是两个有质量的物体之间的吸引— —任何两个有质量的物体。

So, it generates a huge attractive force.

所以，它产生了巨大的吸引。

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

我们它们是吸引，它们存在于所有有质量的物体之间。

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

是一种吸引，因此具有质量的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，如果你碳的数量，你就可能存在的吸引的数量。

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

因此，球处于地球的引场中，并受到引的吸引。

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.

对于非常小的动物来， 它们所需要做的就是利用水强大的表面张，即液体分子之间的吸引。

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，物理学的四种基本之一是强核，这是一种作用在原子核中的质子和中子之间的吸引。

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的作用，表面张是由水表面的水分子之间的化学键形成的吸引。

And the decrease in radius from  left to right is due to the attractive force between the protons in the nucleus and the  electrons in the shells.

而半径从左到右减小是由于原子核中的质子和壳层中的电子之间的吸引造成的。

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引，它们必须具有相反的净电荷，因为它们正在经历吸引的电。

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，球处于地球的引场中，因此它感受到了朝向地球的吸引，并且球落到了地面上。

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.

你可以在泥土、木头或混凝土等坚固的地面上行走， 因为分子之间的吸引足以它们固定在适当的位置。

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引中心时， 一个世纪的吸引自身平方以得出下一个世纪的吸引。

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.

运动是科学的最终对象，运动的量度有很多种；但是思想和物质一样，真正的衡量标准是天文学意义上的质量——吸引的总和或差异。

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.

两个柱状的铝电极间隔约50纳米，当电压在这两个电极之间时，它们就相互通电，在二者之间形成一股引，直至达到一个临界点。

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.

人们通常再次回避这个问题，认为他获得了是理所当然的。一种动学理论，根据质量定律吸引分配给相对的物体，理所当然地认为自然吸引人。
