核心畫面
Think of holding two magnets the wrong way round. Nothing touches them, but something between them pushes, and the closer you bring them the harder it pushes back.

可以想成手上拿著兩塊磁鐵，方向擺反。中間什麼都沒有，卻推得開，而且越靠近推得越用力。這個「互相推開」的畫面，就是這個字裡面的東西。後面每一種用法都是同一股推力的不同版本：物體之間的力、表面把水彈開、還有一個人整個身體想往後退。From the word’s history
The packet traces the word through Middle French repulsion to Latin repulsus, the same family as repel and repulsive; the shared picture is being pushed away.
資料來源把它追到中古法文 répulsion，再到拉丁文 repulsus，和 repel、repulsive 同一家，共同的畫面就是「被推開」。
Wiktionary etymology_text supplied in packet (kaikki:3f6f69a190036ae4:1167566724): Borrowed from Middle French repulsion, from Late Latin repulsio, repulsionem, from Latin repulsus.
