Could you share some of the links to any practice tests on specific units? I am currently studying Topic 4 and Topic 9 and I am taking a test this Thursday so is there any links to use. Thanks hope you reply.
Hi there! Sure thing... here you can find many practice questions grouped by topic: studynova.com/quiz/physics/ (including worked out solution). Not all of them are free but many are! Good luck with your studies!
I just wanna say that everything about the video is great...but if you could just use a more complex example it would be better because the questions aint always so easy just hope you can do that thanks
wait in at 5.16 you can see that the smallest and biggest v dont have the same amount of numbers after the decimal. that alters my answer all together does that make my answer wrong. cuh my Δv = 1.42625
So if I were to multiply a number like 7.0cm +/- 0.5cm by 3... like finding the volume of a cube... Following Dy = Da + Db, would it just be Da * 3? Being 21cm +/- 1.5cm?
No one covers what to do when the number just AFTER the significant figures does not round up so if you have one significant figure and your uncertainty is 2.02 is your answer 2% or rounded up to 3%?
If the number after the significant figures doesn't round up, then there is no need to round up at all. In you example, 2.02 would just be 2 (if you wanted 1 sig fig)
I was starting off with the equations that the IB uses in the formula booklet. I'm well aware that there are different methods to use - for example at Uni in Physics classes, we were always using derivatives as well. Cheers, Mitch

Thank you!
how'd your test go? four years later lmao
@@wxrlp i wonder how it went as well, 5 years later
@@mimshio I'm also curious about the result, share it with uss
THIS IS THE BEST UNCERTAINTY VIDEO I'VE COME ACROSS THANK YOU SO MUCH
Guess you can say that with certainty
@@mikeoxlong2077 😂
oh my god i can’t thank you enough i hope you have the best life ever you deserve everything
Wow, thank you so much for the endorsement! I'm so glad you can benefit from the videos! Cheers, Mitch
Thank you so much for this..I like the way you present it, especially the side talks with yourself!
ive been bashing my head around for hours glad i found ur vid
I'm glad you found it too! There's lots more on the same channel - playlist for every topic in Maths AA SL, Maths AI SL, and Physics SL and HL
YOU ARE A GENIUS! Thank God you are alive!😍😭😭😍😍😍
3:53 how most remixes sound today
Thank you bestie I am a year one engineering student and the doctor didn't explain this well but you did it perfectly 😭❤
I'm so glad it was helpful! Cheers, Mitch
Thank you good sir, Took me so long to find a video that uses the uncertainty equation!!
Thank you so much. You just save my summative assessment!
Happy to help! Cheers, Mitch
Finally someone who makes things simple geez! all the other videos are like rocket science...
rocket science aint that hard. rocket engineering is tho
i searched up osc and this was what i found WHERE IS MY BEEFYDIE
now we know this legend's name... Mitch Campbell.
Thanks you so much , my doubts are finally cleared
Happy to help! Cheers, Mitch
You are so so so so so so so so AMAZING. Thank you so much 🤗
you are my king
Sir your video was reallygr8 and helped me a lot in understanding uncertainties INCREDIBLE VIDEO SIR THANKS A LOT
OMG I FINALLY UNDERSTAND!!!!!!!!!!!!!!!!!!
Yay! That makes me so happy to know - good luck with your studies! Cheers, Mitch
Thank you very much
You are very welcome! Cheers, Mitch
best guy even
Gee, thanks! Cheers, Mitch
Amazing
Thank you! Cheers, Mitch

just hope you can do that
thanks

Good video. What if your answer is derived by ab - c ? Would you then combine both uncertainty equations to derive the absolute uncertainty?
Oh my god thank you
You're so welcome! Cheers, Mitch
As of now I believe I can solve the exercises from what I learnt but it feels like I memorized the steps instead knowing why we solve it this way
Keep up the studying - you'll hopefully get to where you understand it better rather than simply memorising it :) Cheers, Mitch
Why didn't you make an average between vmax and vmin for accuracy?
I love this video
That's wonderful - I'm so glad you like it! Cheers, Mitch

I wish you become my university lecturer.
how did he get the ms-1 ting???????
it means meters per second. its the same as m/s. 1/s is the same as s^-1. so ms^-1 is the same thing.
You started explaining things clear then when reach the second example you lost me
nice.

That uncertainty equation is not correct. It should be the square root of the sum of the squares of the uncertainties divided by parameters.
