What does a delta mean in science?

What is the unit of delta-v?
Delta-v (more known as “change in velocity”), symbolized as ∆v and pronounced delta-vee, as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver.
Why does delta mean change?
It’s used because of the word difference, whose latin etymology happens to start with a “d” also. Differ comes from the latin word differre, derived from the word ferre which can often be translated by “carry”. Pretty much every word which contains the word “differ” is derived from this.
What do the symbols δ+ and δ signify?
δ− represents a negative partial charge, and δ+ represents a positive partial charge chemistry (See also: Solvation)
What is meant by partial charges δ and δ +?
Percent Ionic Character of a Covalent polar Bond
Recall that a lowercase Greek delta (δ) is used to indicate that a bonded atom possesses a partial positive charge, indicated by δ+, or a partial negative charge, indicated by δ−, and a bond between two atoms that possess partial charges is a polar bond.

How do you calculate delta-v?
The following formula is used to calculate the delta-v of a rocket:
- ∆v = Ve * ln(mi / mf)
- Definition:
- Example:
- ∆v = Ve * ln(mi / mf)
- ∆v = 500 * ln(1000 /400)
- ∆v = 458.14 m/s.
