Calculating Uncertainties

IB Uncertainty Calculations

[indentedcode]

thnx A lot for sharing the video. it helped me a lot tomorrow i m having exams. i was bad in solving uncertainty but now i can solve every problem of uncertainty. God Bless You.

Can we just appreciate how perfect the number 7 he wrote at 2:29

you sir, just saved my bacon: I've been struggling for a while with the explanations offered at uni and you sum up everything rather conveniently in the space of 10 minutes. Thank you very very much!

Thank u my guy 🥺🥺🥺 am doing A level and I couldn’t understand how my teacher explained uncertainties, but thanks to you i know how to do them now.Love from Birmingham 🇬🇧

Thank you so much sir, i got a 100 on my physics 11 just with watching this video the night before my test

This video was so helpful and I fully understand it now. Thanks for sharing your knowledge.

at 09:57, why g/cm3 replaced to only grams?

This treatment of uncertainty is a bit simplified. For the most part, it will result in somewhat larger uncertainty values than the standard treatment will give. Primarily, you are adding uncertainty components like they are along the same axis, but really they should be added like they are orthogonal components of a vector, and therefore should be added with pythagorean theorem.
example: Delta(x+y) = sqrt[ Delta(x)^2 + Delta(y)^2 ] instead of simply Delta(x) + Delta(y) as you have in the video. Similar issue applies with multiplication and division.

How did you get the plus/minus values?

Read comment by Marauder234(for future reference). He is talking about the example at 9:14

Thx, i needed this for my physics depth study

[tanisha]

first day of IB1 Chem and this saved me! I was so confused until I found out that it was just the uncertainty percentage all along!! :((

Thank you for saving my physics grade❤

5:24 What just happened here? The sound almost went insane

[khadeejaakhtar]

this helped me so muchhh!!!! thank you!

[msduff]

thanks I think i get it now... will be able to finish my assignment cheers!

[sreyabanerjee]

Thank you so much for the explanation.

Hi, if I'm calculating an uncertainty of a formula like this: (44.28+|-3m)/sin(71+|-2°) is the way of doing it the same as you showed?

[PrabinDhakal]

is there some published paper or some book that verifies the video?

[akolangto]

Thank you very much sir! This helps me a lot.
