Walter Lewin, thank you so much. You are a champion! This video made me feel like I can do this semester's work if I keep on seeking help and working my way forward bit by bit.

Sir kindly make video on uncertainty measurements from basics

Si how you write the error in the distance as +or-20

Also, say I have datas for x and y alongwith the respective uncertainities. If I have to plot x vs log y, then how do I calculate uncertainity in log y? For instance, if y= 54.3 +or - 0.5, then what will be log y?

So, are you saying, only use the poor man's version in this class, and later, when you're working, use the correct version? And, that correct version, I'm guessing, is instead of adding uncertainties you take the square root of the sum of the squares?

CAN U TELL HOW TO CALCULATE UNCERTAINTY OF MEASUREMENT LIKE MEASURING TAPE , MICROMETER & VERNIER CALIPER

Sir i meaur the lenth of a page. It comes out to be 15cm. How i can tell about the error in this messurent

your error is the smallest unit of measurement you used divided by 2.
Sir but how the error % in b square is 20%.. Sir Pls elaborate

Max error 10+1 = 11/10 = 10% more Min error 10-1 =9/10 = 10% less On average, the error 10+-1 =10% Max error (10+1)^2 = 121/1000 = 21% more Min error (10-1)^2 =81/100 = 19% less On average, the error 10+-1 =20%

For divisions and multiplications we add %uncertainty, b 1/10*100%=10% squaring b become 10%+10%= 20%
