this resonated for me, quite hard actually. there's the famous quote which has always stuck with me on this stuff slow is smooth, smooth is fast.

thinking about it a little more, i would personally prefer to use the term momentum rather than velocity or just plain speed -- we accrue more mass by adding code, features, etc. and shifting direction/increasing speed are both harder with greater mass.

I think mass and momentum are appropriate. I use them when talking about this too.
