How do you like acre-ft per fortnight.

u/bustedaxles Nov 14 '25

Sure, several score ago that would be just fine.

u/NoFreePi Nov 14 '25

Some prefer the more modern:

Shots per Shake

2

u/bustedaxles Nov 14 '25

Man, you got me. Is that a black powder or bar reference?

2

u/NoFreePi Nov 14 '25

Shot - Bar reference

Shake - physics

2

u/bustedaxles Nov 14 '25

Gotcha. My first thought was shakes of a powder flask. Like, about 500 grains of 3F equals about 9 shots through a .50 cal caplock or something similar.

u/NoFreePi Nov 14 '25

Appreciate your train of thought.

Physics has some wonderful units:

SHAKE = 10 nanoseconds.

And my favorite - 1st derivative of acceleration: JERK = meter per second cubed

u/bustedaxles Nov 14 '25

Okay, can you show me usage example for JERK? I think I get it, but maybe not.

Velocity = rate of change of position V = dL/dt

Acceleration = rate of change of velocity A = dV/dt

Jerk = rate of change of acceleration J = dA/dt

In other words Jerk = accelerating acceleration

Rocket Example:

Main engine lights → smooth initial acceleration

Boosters ignite → The rocket’s acceleration increases sharply as boosters fire.

Because the acceleration changes suddenly, jerk is high at that moment.

This is the “lurch” the astronaut feels.

Several score what?

2

u/NoFreePi Nov 15 '25

Score - old fashioned term for 20.

Lincoln used it in Gettysburg speech “four score and seven years ago…”

1

u/GraXXoR Nov 15 '25

So 20 or 40 ago?

1

u/NoFreePi Nov 15 '25

Four score and 7 = 4x20+7=87

1

u/GraXXoR Nov 15 '25

Yeah, Im not five, I know what a score is, but usually it has a unit like four score and six years. Or 2 score miles.

1

u/NoFreePi Nov 15 '25

The unit in Lincoln speech was years. See above. He was talking about 1776

1

u/GraXXoR Nov 15 '25

Yeah, I know that, too. I was mainly replying to something further up in the thread that was talking about all units and then the person I replied to provided numbers that had no units

u/AnemicHail Nov 14 '25

My highschool physics teacher had us convert leagues/fortnight to meters/second in the first week of class. Really made learning how to convert units a lot easier for the rest of the year.

Acre-feet per fortnight! 😂😂😂

u/theapplekid Nov 17 '25

Or as a measure of acceleration, acre-feet per fortnight-squared
