PHYSICS - ESTIMATION:::PLZ HELP

[XPFMember]

Assalamoalaikum!!

the syllabus outcome 1(g) make reasonable estimates of physical quantities included within the syllabus

i wonder if anyone has some trick for this i'm really bad at estimates any help?..bcoz u get like a 4 mark question and i dont want to simply lose marks for just a simple thing

it doesnot always come..!! and there are some estimate u can compare...as for example..mass of an apple....now think the number of apples u get in 1kg...u must have bought it....it usually will b 4 to 6 on average...so..simply considering 5 apples in 1kg..mass of an apple=200g...........and many more..this is just an example...!! now other one is..."the diameter of a hair".....now i think u cannot do a comparision here..!! so better practice all past papers....and ask ur teachers what are the likely questions to come...and memorize it...for the hair type of question..!! i did the same..

you need to practice a lot of past papers and use common sense to give the answers.
For eg,
Mass of pen: 20-80 g
Mass of hair: somewhere 0.01 g
They don't want a pricise answer because objects have variation. They just want to check how you think with you see an object.

Waalikumussalam!
By the time you complete your A2 physics,you'll be able to get all of them right!
GOOD LUCK!

And if you have estimate the thickness of a sheet of paper..... Count the number of sheets given in your exam...... Then measure the thickness with a scale..... and divide it by the number of sheets.....
