Delta-v is defined as "change in velocity", ie. how much a spacecraft can change its velocity. I think you're talking about relative velocity.

- tyre 11y agoI believe GP was referring to delta as in mathematics, which refers to difference and not necessarily change. So the delta between +7km/s and -7km/s is 14km/s. You are technically correct, though based on common usage patio11 got their point across.
