Is there a good word for change in velocity, but not over time? That is, position is to displacement as velocity is to what?
This old question (2012) came up in suggested results. While it is a single word request, I would consider it to be more physics-oriented than EL&U-oriented given the topic and its narrow usage.
While it's not hurting anything here on EL&U, should I flag it for migration? As one commenter remarked about the accepted answer,
This is essentially a science question, not about language. See below: Δv is a notation, not a word in the English language
And how should we handle such overlap in the future?
