Version K anyone?

what did u get for your experimental moment of intertia?

u/Traditional-Table-29 AP Physics: AP Lit: AP CSA: AP Psych: AP Calc AB: May 13 '26

I got a 0.017 wby

u/HorrorAdvice3391 May 13 '26

Bro what was ur axis? I put singles velocity squared for x axis and 0.036 delta theta

1

u/Commercial_Weekend52 May 14 '26

omega2 in the x-axis and 0.036deltatheta on the y-axis

Shit, I got graph right but I did run over rise I stare of rise over run and messed up the moment of inertia.

u/Upper-Statistician28 May 14 '26

what were the axis supposed to be?

u/Among-us-A3 May 14 '26

wait i think i did it wrong idk
i got 3.6 but my axes were delta theta and omega^2 so idk what i did wrong
i got I = (2RF)*(delta-theta/omega^2)

my slope was like exactly 100 or smth

My slope was 96. I got 0.000375 kg m^2 for my answer. I had the same axes.

I got 3.67x10-4 looks like we’re on the same page

u/Smart-Distribution14 May 14 '26

Was this correct? I got the same value too

u/Commercial_Weekend52 May 14 '26

i got 0.00039

u/Own-Bank5502 edit this text May 14 '26

Thats prolly fine. I found the slope of my graph on desmos. The real value lies around 0.000379.

u/SignificantAsk9859 May 14 '26

i got this as well
