ANSWERING TECHNIC PAPER 3 SECTION B

1. Find the MV and RV which can be measured only
2. When make inference relate the MV and RV.
Eg: RV depends on MV.

3.Better write hyphotesis statement use the word “When MV increase/decrease, the RV increase/decrease
4. Better draw and label diagram first before write procedure and material.If enough time listing the complete list of
material/apparatus.The apparatus has been drawn must functioning.


4.State the method of controlling the MV - state the valueState the method of measuring the RV
5.Repeat the experiment at least 4 times eg : 30 cm,35cm,40cm,45cm
eg 25 cm, Sketch graph with axis
6. ANALYZE DATA
write x-axis MV with unit
Y – axis RV with unit
No need plot

answering technic paper 3 Physics

SECTION A:
1. prosedure to Tabulate data
Shows a table which have quantities of physic.
Unit in column must correct and , value must consisten( same decimal place)
The decimal place (dp) depends on the instrument

2. Extrapolate graph –make clearly -calculate gradient of graph must draw at least 4cmx 4cm triangle -Correct substitued in formula -don’t forget unit WHEN calculate, base from y axis and x axis

3. DRAWING GRAPH
Draw at least IN 50 % of graph paper
State the unit of graph clearly
Both axes with the even and uniform scale
All points correctly plotted
A smooth best fitted straight line
