Hi guys...hows your revision?
.. trial exam's fever is around the corner..its temperature is approaching the boiling point now :)
Hope u are doing well with your revision..
Here i wanna share some short tips about plotting graph in paper3 .
When u are being asked to plot a graph for section A paper 3, please make sure u include the following item:
(i)Title of graph
-Usually we start the title by mentioning the "quantity in Y-axis VS quantity of x-axis"
-Example:
Title of graph: Graph of V versus I
V represents Y -axis, I represents X-axis
(ii) Labels of x-axis and y-axis and units
-Make sure u include the labels & their units for each axis. Usually,
x-axis represents the manipulated variables
y-axis represents the responding variables
(iii) The vertical and horizontal scales must be even.
-Please choose the right scale based on the data given. Your scale should produce a larger graph
-Choosing right scale is important in order to let u to plot the points easily
(iv) Size of the graph is about ¾ of the graph paper.
-Make sure your chosen scale will produce a larger graph which occupies about 3/4 of the paper
-If your graph's size is less than 1/2 of the page..u better redo the graph ;)
(v) Dont forget to write values for the origin of the graph
Most graph starts with zero but there's case that some graph starts with a nonzero.
(vi) Use small cross mark (x) to plot the coordinates of the point in the graph
Make sure u plot the right point according to the data collected in the table.
Gradient calculation tips
In section B, they always ask u to calculate the gradients. While doing it make sure
-The chosen point should at least have a distance equivalent to 1/2 of the length of the graph
-please draw the triangle between the chosen point
For curvy graph, u need to draw the tangent line to find the gradient.
I think that's it for now, may it be useful to those who is weak in paper3.
(ps: For those who wants to copy this tips to your blog, make sure u include my link as well :)

- I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect.

hai...i wanna ask u tat how to draw a velocity-height graph?
tomorrow trial~~johor
hmm..its hard to draw it here, but ifa ball falls frm higher height..its veocity increases,& the height decreases.In othr words the velocityincrease as the height decrease.
I got a question here!
our chemistry F5 chapter one, a experiment to study the concentration of Na2S2O3 and the rate of reaction, may I know the graph : concentration of Na2S2O3 against time, the time should be X-axis or Y-axis? Time is the responding variables! I heard my tuition teacher said, those book are wrong! it should be time against concentration, which is mean, time should be Y-axis, concentration should be X-axis! Help!
supposed tis is a physics blog, not chemistry..sorry i couldnt answer that
Is it okay to draw the graph horizontally?
it possible in P2, but dpends on topic..but through my experience u hardly find this kind of graph in Paper 3..
