物理单位“牛顿”，是以物理学家伊萨卡牛顿命名的，一牛相当于一颗处于地球表面苹果因重力因素而所受力的大小。

The newton, named after the physicist Isaac Newton, is approximately the force exerted by gravity on an apple at the Earth’s surface.

在这一节中，我们暂时离开牛顿定律来讨论一下单位问题。

In this section we depart briefly from the subject of Newton's laws to discuss the question of units.

But we get tired of saying that long expression, so we're going to call that a Newton, right?

但我们不想说得这么复杂,所以把这个单位称为"牛顿",对吧

如果是你发明的,我们就用你的名字当单位,但这个单位是他发明的,所以叫它牛顿,一般用大写字母 N 表示
