Calculating uncertainties [IB Physics SL/HL]

We're so excited to be able to share our exams with you!

Cheers, Mitch

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.

THIS IS THE BEST UNCERTAINTY VIDEO I'VE COME ACROSS THANK YOU SO MUCH

[Serpgamer]

Thank you so much for this..I like the way you present it, especially the side talks with yourself!

[kevinsimms]

YOU ARE A GENIUS! Thank God you are alive!😍😭😭😍😍😍

[mariamcu]

oh my god i can’t thank you enough i hope you have the best life ever you deserve everything

[brandongregory]

Thank you good sir, Took me so long to find a video that uses the uncertainty equation!!

[peaceandlove-hb]

Thank you bestie I am a year one engineering student and the doctor didn't explain this well but you did it perfectly 😭❤

[hexonedits]

ive been bashing my head around for hours glad i found ur vid

[bogdan]

Finally someone who makes things simple geez! all the other videos are like rocket science...

[ibhadeerua]

You are so so so so so so so so AMAZING. Thank you so much 🤗

[dzsdnxp]

Thank you so much. You just save my summative assessment!

[bhavyajain]

Thanks you so much, my doubts are finally cleared

Sir your video was reallygr8 and helped me a lot in understanding uncertainties INCREDIBLE VIDEO SIR THANKS A LOT

[SAAD-ocnu]

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

[julienelson]

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%?

[hqppyfeet]

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?

[ABM]

Good video. What if your answer is derived by ab - c ? Would you then combine both uncertainty equations to derive the absolute uncertainty?

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
