Got some stuff here bout phy prac. Impt stuff about the graphs... Actualli all little points but all impt to get a good mark.
Have a look:
-Use even scale don ap and use funnie scale like 1:13 or something liddat if u do, u are juz giving urself a headache! =)
-Rmb that scales don have to start from zero. that way, u can make full use of the whole graph paper and draw a BIG graph... HOWEVER, scales have to start from zero if the qns after they ask u to draw the graph goes something like this... Find__ when the graph cuts the x-axis/y-axis then u need to draw the graph to start from zero.
-Every 2 big squares,(i.e 2 cm) need to have at least one marking on the scale.
-Don't need to write scale
-Check! If the next qns directly ask u to find the gradient, the graph is most prob a straight line. If ask to find gradient of tangent to _____ point then obviously it is a curved graph!
-The gradient triangle should be at least 2/3 of the graph that is drawn.
-If u draw a straight line graph, should have at least 5 points. If it is a curved graph, 8 points is the best.
-Rmb to write units on the graph axis (i.e P/W)
Hmm... that's about all...
It is more than i can ever ask for... Thanks. =)
