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!
