I get that repeated measurement can produce a more accurate result, but how does it reduce absolute uncertainty? as uncertainty is found by range of results /2
when you repeat measurements, the results will be more accurate thus smaller range of results as errors can be eliminated no? and thus smaller absolute uncertainty? not too sure tho
@@pohsy3103 Hi yes that is correct, the more repeats, the greater concordancy and precision - allowing you to remove anamolies and decrease your range.
Great video thanks so much but on another video it said the absolute uncertainty of a gradient is just the difference between the line of best fit and line of worst fit. Is this wrong, as here it says it’s the difference divided by 2 (at 29:52). Why is this different from the absolute uncertainty of y intercepts which is just the difference between best and worse intercept (at 29:59).
First time watching your vids, this is really helpful !!
THANK YOU YOUVE SAVED MY A LEVELS
GL YOU GOT THIS
Thankyou, good video!
Thank you!!

It’s line of worst fit - line of best fit over line of best fit x100
@@liamfinley723 that’s only for the percentage uncertainty I think, not the absolute uncertainty
great

I’m sorry but I think it’s the nature of the subject but physics is simply boring when put into a video
Nah this guy is just boring, there's many other more entertaining videos that teach Physics
Try Kurzgesagt !! I think they present physics in a rather interesting way
@@violettecoffeereally helpful for alvels tho arent they 😐

34:43 why -c?
How do you workout absolute uncertainty
1/2 multiplied by the range of values
@@Sohamsta safe
for 9:20 is it possible to just draw a circuit diagram?
Yes but it must be clearly labelled

Im so fucked I don't even understand astro either paper three is what will fail me in physics and get me an E
😥
me this year (exam in under 10 hours)
