Question on a Spaceship Drive -- changing acceleration is called what?

[ckirmser]

I couldn't find a relevant forum - that I could recognize, anyway - so, if this is in the wrong place, please feel free to move it to a more appropriate forum.

Ennywho, I have a question on terms.

Let's say there's a space probe's propulsion system that is currently providing an acceleration of 1G and it is being increased to 2G. The process of changing from a 1G acceleration to 2G takes, say, two minutes.

What is that rate of change from 1G to 2G called? Is there even a term for it? Are there any related formulas? Does it have something to do with specific impulse or any of the other common propulsion terms or procedures?

Thanx in advance!

Is there even a term for it?

Omigawd, I'd've never even thought of that term. I would've thought something a bit more - well, scholastic like "Oppenhoofer's Second Law of Dynamic Motion" with the term called "emphatic impulse," or something.

But, thanx, A.T., just what I was looking for.

Then check out the names for the even higer derviatives of position:

The higher in derivative you go, the less this is used in real physics and the more it is used to win bar bets.

I guess my classes in quantum mechanics should have given me a hint that physicists have a wacky side - I mean, with the way they name particles...
