Recycle Bin Posted October 18, 2016 Report Share Posted October 18, 2016 I have tried everything to understand the Data Analysis/Uncertainties and Errors (Chapter 1) topic of Physics. All I understood in the past papers were the proportionality questions but I don't know how to find uncertainties/fractional uncertainties/absolute uncertainties/percentage uncertainties AT ALL. I just don't understand what formulas to use for the uncertainty questions! They pop a lot so please help. P.S: I read the textbook, but it doesn't really help me solve the past paper questions. 1 Reply Link to post Share on other sites More sharing options...
najem Posted October 20, 2016 Report Share Posted October 20, 2016 You should check out Richard Thornley. He does Chemistry but has some nice videos on uncertainty. Here is the link to the playlist. And here is the video that explains the problem you mentioned. 2 Reply Link to post Share on other sites More sharing options...
samim Posted October 31, 2016 Report Share Posted October 31, 2016 Familiarize yourself with the notions of uncertainties, the way in which you may solve uncertainties. I actually found that topic easy because we had lots of experimental practice with collecting data and calculating uncertainties in both chemistry and physics. If you didn't do this its fine, just grasp the procedure which must be taken solve the uncertainties, it should become easy after some doing practice and self-reasoning. There are a few ways to get uncertainties so make sure you have a solid understanding of one way, which you can always implement and learn the rules that come with uncertainties, they are important. 1 Reply Link to post Share on other sites More sharing options...
