I've attached a pdf containing all the experiments that you need to know. Although I find that learning the experiments from past papers is much better, because the information in the pdf is very vague imo.
Plus does anyone have notes on uncertainty?
Hey, how's revision going?

I have done papers from 2009 to 2015 and pray that they give an old experiment :tongue:

how do u find the uncertainty of a specific instrument? or are there standard values for each one of them? if so could you list them!!!!:redface:

Ok there isnt uncertainty in apparatus its in the reading so for example if u measured 50cm using a metre rule (precision 0.1cm these are fixed values for different appratus look them up) so if u have to calculate percentage uncertainty u would do 0.1/50 multiplied by 100% to get %age uncertainty hope this helps if i said sth wrong others plz help :smile::biggrin:
