“库仑引力”是天文学专有名词。来自中国天文学名词审定委员会审定发布的天文学专有名词中文译名,词条译名和中英文解释数据版权由天文学名词委所有。
我们昨天学习到,我们有库仑引力,之前你们学过的。
And we saw last day that we have a Coulombic force of attraction which you have seen before.
当它们真正离得很近时,假设有一个带正负电的电荷,带有库仑引力。
So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.
然后说势能,位能其实就是,由电子和原子核之间的库仑引力而形成的能量。
And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.

It plays a big role in gravitation, in the Coulomb interaction.
它在引力和库仑力中都起着重要的作用
