Is it possible to study A2 Physics without AS physics knowledge? Is A2 Physics very much related to AS Physics? Need answers frm u guys quickly。It's urgent!!!Thanks

No, i dont think so, why do you want to do it?Is it possible to study A2 Physics without AS physics knowledge? Is A2 Physics very much related to AS Physics? Need answers frm u guys quickly。It's urgent!!!Thanks
Isn't Physics over with ?Guys I have a doubt in the telecommunication chapter. When concerned with signal attenuation and noise calculations always involve the unit decibel (dB), and there is one question asking why use the decibel as unit. I have no idea at all with this question. Can anyone explain to me the point? Thanks a lot.
I'm sorry?Isn't Physics over with ?
Physics p4 is over, right ?I'm sorry?
Okay I get it. Thanks.Physics p4 is over, right ?
Anyway, its because the values involved are very large to be handled!
So logs are used and that is why a new unit bel is used!
1 decibel = 10 bels
Right, but better to focus on other exams, huh ?Okay I get it. Thanks.
Physics P4 is over but I still need to get clear some points. It's not just for the exams, right?
physics p5 are kinda easy...Drowning in paper 5... Starting to study for it today for the first time !!! :S
No clue how to prepare for it or how to solve the questions... ugh..
Then please share the exact steps you used to properly prepare for this paper from the very beginning.physics p5 are kinda easy...
For question two..Then please share the exact steps you used to properly prepare for this paper from the very beginning.
I just feel its kinda time-consuming to know all the experiments possible so that we can explain the procedure...
awesome, seems I understand question two properly then. ThanksFor question two..
you have to draw two lines . One the best fit line and second the worst acceptable line. The worst acceptable line is the line from the lowest error of first point to the highest error point of last point or vice versa.
To calculate uncertainty in gradient = Gradient of Best fit line - Gradient of worst acceptable line
and to calculate the uncertainty in y-intercept = y-intercept of Best fit - y-intercept of worst acceptable line.
If you have to find a value using gradient and then you are asked to find uncertainty in it then :
e.g gradient = p/v and have to find p
you will find p using gradient of best fit line and then find a second value of p using the gradient of worst acceptable line
so the uncertainty in p is= first value of p - second value of p.
Np.. and i dont know how to prepare for vhem p5..awesome, seems I understand question two properly then. Thanks
But then I guess my problem is with question one. Too many experiments to learn. Cant believe we have to learn soo many experiments.
If you have any steps for me to follow to learn Question one, or shed light on the steps you used to study. That will be helpful.
Thank you for your time Much Appreciated
Ok now I know the tips, but how did you know all the experiments? Do you have link or website ?Np.. and i dont know how to prepare for vhem p5..
Ppaper 5 Tips Question 1
aoa wr wb!Ok now I know the tips, but how did you know all the experiments? Do you have link or website ?
I am pretty sure that you did not ONLY study those tips? I need a compleete study guide on paper 5 especially on the experiment in Question 1.
How can I know all the possible experiments for each situation????? Im really confused!! There must be a shorter way.
Thanks!
i never studied any experiment.. most of the experiments in question 1 are very similar to AS practicals. so , i kinda know what need to be done. Plus , as user said that read the question and think and then divide to fulfil the requirements.Ok now I know the tips, but how did you know all the experiments? Do you have link or website ?

paper 5
omg, you guys make it look soo easy! Man I must suck badly. Sometimes I dont know what can be done to investigate the problem, so I would prolly lose alot in method of data collection...yup dividing things is the best thing...makes it a lot easier..
