Visit //ilectureonline.com for more math and science lectures! In this video I will multiply 2 lengths when there are uncertainties in the measured length.

+xLegiolx Found it. Thanks

3x10^2 = 3 x 100 = 300. I guess you mean 0.3 X 10^2.ï»¿

+Pascual Chavez 3 x 10^2 = 3 x 100 = 300 0.3 x 10^2 = 3 x 10^1 = 30

Hi Lisa,
Thank you very much for uploading this video. I am currently in my 5th week
of the IB program in Australia and my Physics test is this coming week so
this has been a massive help to me!!
Thanks again.ï»¿

Excellent demonstration! Thanks for making it so complete. : )ï»¿

thanks a lot ma`am. ^_^ :)* ï»¿

Thank you! SO HELPFUL.ï»¿

How to multiply quantities with uncertainties WLU PC131 The original document can be seen here: //denethor.wlu.ca/pc131/uncbeam_mult.pdf.

so badï»¿

If you add or subtract data then the uncertainties must also be added. Multiplication or division of data means that the percentage uncertainties must be added.

Hi Mr Thornley! Just wanna ask what if the calculation involves both
addition and division at the same time? How should I do the uncertainties?ï»¿

+Hiu Ying Bernice Chow - Bombax calculate the addition first (follow decimal places) then do the multiplication (follow the significant figures)

Can you explain the differences for IB physics? ï»¿

nope - no idea!

where did you get the 0.500 kg/l from?ï»¿

1.00 divided by 2.00 = 0.500

Mechanics Minilesson with Prof. Adam Burgasser. In this first lesson, I discuss significant digits and uncertainty and how they are related precision and accuracy.

Constructive criticism: I am having a hard time following this. I am very
familiar with significant digits, but when you speak of precision,
accuracy, uncertainty, and how they relate to each other and to significant
digits, I feel like you sort of throw the terms around without really
explaining.

No comments? Well here is one. Hope that makes you happy professor, I
basically should now get an A in 1a.

It was so hard to focus with the breast feeding video on the side bar.

Just wanted to say thanks! Your video helped me a lot!

Excellent. Thanks. A very clear and precise lesson.

easy to follow and understand...liked it!

Thanks

Introduces both statistical and worst-case formulas for propagating uncertainty through multiplication/division and addition/subtraction calculations. Uses the ...

What about calculating the "propagated uncertainty" when we have a
complicated formula (not a simple formula like that presented here for
multiplying length by width to get area of desk table)? This complicated
formulas are the real headache of all serious users.ï»¿

From where did you get the 3 mm uncertainty of the length and the width? -
If we know this 3 mm uncertainty everything is straightforward, but a
priori we do not know this 3 mm value.ï»¿

Where can we stay "tuned"? There is is noway to find your next video, Sir.ï»¿

I've been searching for this for 20 minutes. Thank you so much.

Thank you very much! You explained it very clear!ï»¿

If you add together or multiply together two numbers, both with uncertainties, what is the uncertainty of the result?
