All of AQA Measurements and their Errors - A Level Physics REVISION
Рет қаралды 76,284
Күн бұрынIn this video I go through all of AQA measurements and their errors for use as A Level Physics revision. This video is not only vitally important for preparing for Paper 3 and the practical physics skills but it also has essential information for anyone starting A Level Physics.
I recap base and derived units as well as the common prefixes. There are random and systematic errors and how to minimise these, key words like accuracy, precision, repeatable and resolution. I then go through absolute and percentage error for single and repeat readings (for both readings and measurements) as well as percentage uncertainty in gradients. There are the ways that errors and uncertainties are combined to give the final uncertainty in a reading.
Don't forget to subscribe on KZfaq and also sign up to my A Level website to find hundreds more videos.
Thanks for watching,
Lewis

If I may be so bold, I think precision = the number of decimal places your data is measured in rather than the consistency across a data set. Consistency across a data set is called 'reliability' I think

Hi there, I find your videos well explained and very informative. Is there a possibility that you could make it possible so that I may be able to download your mind maps for each of your videos? For example, when making a video, you would take a picture of the mind-map and put it on your website so that we can download it. That is if you have any time. Thank you, Sir!

Answer this question for me, please, is a head scratcher: 1.0 cubic centimetre (cm^3) of a solution contains 0.010g of salt. What is the mass of salt contained in 1 cubic decimetre (dm^3) of the same solution? Textbook says 10g but I disagree, my answer is 0.1g Which answer is correct and Why???
