how was physics practical 32

what 4 improvements did you guys put ? I struggled to come up with a last one.. pretty confident in my first 3.. so what did you guys put for it ?

Oh and my values of k were almost identical :/ that looks fishy lol,,, anther thing i'm a bit worried about is the table for part 1.. you normally have to put record values.. but how and where were u supposed to record them ? in the table ? or make a separate table ?

soo watt...most of our y intercepts were very very close to zero..so i think there should be a range which can go down into da negatives...n jst because a teacher did it doesn't meen he should be getting da exct answers...my teachr also did it...she got a positve y intercept...doesn't meen tht it's rite jst becuz she did it...do u have anyothr proof???

ok another is that most of the students got it negative and another proof is that the y axis had a very wide range which can tart from 5 to 700 according to the equation (L/2 -d)squared...and by using the equation y=mx+c the y will be negative..but im pretty sure that most of u just lsaw from the graph where the line would pass...and im not sayingi did well in the rest of the exam, i said before that i messed up

guys i want to ask u something.if one gets A in paper 1 and paper2 but very bad marks in paper 3 ,is it possible to get an A in ASlevel.i am really tensed cuz i dont want to repeat it.

naww..i used the equation..n i got 0.0015.or sumthin lyk tht...anywayz..good luckkk..

The guys whose gradient wasn't negative probably didn't draw that good a line of best fit.. anyway I got my gradient as 0.75m... and y -intercept as -0.005m^2.. and im wondering when you repeat readings should the uncertainty just be that of the measuring instrument used or some other thing ?

thats right,,good luckto all of us...and maybe as one of us here said there is a range of error where the y intercept can be between negative and positive!!

i thought the same thing..but face it it is negative and am 100%sure

well i hope you're right....good luck
