    how was physics p51??

    I have to disagree. -Just by noting that you have mentioned mass of load and length of string as constant,,, you gain 2 marks. -w=2pie/T ---> 1 mark - measure T by stopwatch ---> 1 mark -plotting of a correct graph and axis= 2 marks - safety precaution /additional details ---> 3 marks I think...

    how was physics p51??

    Guys. 1) The question clearly asked how Theta varies with Omega. Hence angular velocity is the Independant vairable, while the angle is the dependant variable. You do not change the period. You change the speed, and hence omega changes causing a change in Theta. The experiment should be somehow...

    When do we use an EHT Supply? In which experiments? EHT = Extra High Tension , this means that it has a high voltage and low current? or not necessarily low current?

    I got Paper 51 in 7 hours. How was 52? 51 and 52 are different anyways.

    Physics Paper 5 tips

    Yes for logarithms, the number of s.f determine the number of d.p. If x = 5 s.f ( disregard d.p ) then log (x) --> 5 or 6 D.P! Anyways thanks for noting and reminding others! Jazak Allah

    What is the difference between a coil and a solenoid? Check mark scheme Nov 11 / P51 / Q1.

    If value of T is 2 s.f then logT = 2 or 3 d.p If value of T is 3 s.f then logT = 3 or 4 d.p If value of T is 2 s.f then T^2 can be 2 or 3 s.f and logT^2 can be 2/3 or 3/4 d.p depending on how many s.f used my T^2.

    The number of significant figures of a number correspond to the number of decimal places of the log of that number or one more d.p. For example x = 543.1 ---> 4 s.f -----> 4 or 5 d.p in log(543.1). That should clear up alot.

    I would suggest the use of a motion sensor in line with the motion of mass A. The acceleration would be deduced from the velocity time graph. Using a light gate is also another correct approach but can be tedious while performing the experiment as you need to program them.

    Hello, I study physics at home too! Question one Diagram holds marks depending on the question. Sometimes it ranges from 1-3 marks depending on how many details are required. You dont plot a graph, you just say what to plot on the x- and y- axis and how the graph should look like. Question 2:-...

    Physics Paper 5 tips

    I did , but I dont see any similarity between those experiments and the a2 experiments.. Never was an air track glider or polaristation or signal generation +cro given in any of paper 3 as far as I know.

    Physics Paper 5 tips

    Im just feeling that you surely require prior knowledge of experiments for question one in paper 5. To investigate force and acceleration, who would think of an air glider track :confused:! Projectile motion, wooden board with a small ramp on a side.. its hard to think of such experiments...

    Physics Paper 5 tips

    Awesome, it has been very helpful. Thank you very much! 1-) May you please shed light on the number of decimal places and significant figures? How can we know how many to use? Whats the relation between them? 2-) For Question One, do we have to look for experiments on all the Physics Chapters...

    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... Man I am really like stuck here, I dont know what Im doing is right. Cz I am looking for all sorts of...

    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...

    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...

    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...
