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.

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?

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?

Sir but how the error % in b square is 20%.. Sir Pls elaborate

@Zonnymaka 6 жыл бұрын

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%

@didimalangnyepetsi9038 6 жыл бұрын

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