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
