adj. gravitational
So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.
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 first of all, Cal Tech has a very strong group in gravitational wave physics,
首先,加州理工引力波物理的师资很强,
And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.
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。
