Tips for Paper 3 No 1 and No 2
1. Identity the variable from the text and diagram.
(a) Manipulated variable
(b) Responding variable
(c) Fixed variable (can be measured)
---NOT TYPE OF SUBSTANCE
(d) Observe the diagram measurement
(e) Identity the value in table
(f) Tabulate data with symbol and unit
(g) Plan your graph (unit and symbol)
(h) Determine the relationship from the graph
2. Read the question CAREFULLY
(a) Extrapolate the graph and write the value next to it
(b) Plot biggest triangle and get closest value with unit
(c) Substitute the value correctly with 2 decimal places
(d) Place precaution
Eye Observation perpendicular to the scale of (instrument) to prevent
parallax errors
Off the circuit when measurement is not taken to prevent heating of wires
and cause systematic errors
Repeat the experiment for 3 times and determine the average to prevent
systematic error
3. Tips Paper 3 no 3 and 4.
(a) Planning experiment is the BEST to do and EASY to score but it is also easy to
differ from the main point.
(b) Identify variables from the questions from the statement, CIRCLE UP the
variables involve and APPARATUS GIVEN in statement.
(c) Think what ???? experiment is using given apparatus as a HINTS. Plan and sketch
the diagram of experiment step up.
(d) Write inference, hypothesis and aim FOLLOW FORMAT given.
Underline the variables of MV and RV from the diagram. Use the variables to substitute the
format of Planning Experiment.
Procedure
1. State the initial measurement of MV.
2. State the ways of measurement of RV with apparatus and follow with formula (if
necessary)
3. Repeat the experiment with 4 different MV values. a1,a2,a3 and a4.
Paper 2 Part B
1. Definition – don’t state the formula of the define word
- Write the definition in statement from the formula

2. Comparison questions – must use back the same diagram to compare in
physics term comparison. Quote back the Diagram number, and compare
with statement according to the marks provision.
3. Explanation on aspects given.
Must quote back the aspect given, don’t divert the statement by explaning
other statement of your ways.
Explain the characteristics of the statement given follow ( 1 marks) with
explanation of the benefit and advantages of the characteristics stated. (1
marks)
More explanation are better, usually TWO are more than enough.
Part C
1. Usually calculation, and definition.
Please state formula, working and final results with minimum 2 decimal places and
correct units.
2. Explanation of physics concepts, usually test your understanding of physics formula
relationships.
3. Study specification on the aspects given and evaluate the pictures given to extract the
answer from the information given. Quote the information of point of answer and
elaborate the statement of characterics with physics concept explanation.
4. Try to give TWO explanation of each characterics in a statement. (4 points with 4
explanation) – 8 marks
5. Final 2 marks is the explanation of the BEST suitability and CHOOSE the BEST of the 4
or 5 given examples.
6. This characteristics and explanation can states in a table form. (THE BEST EVER
ESSAY for 10 marks)
7. Choose the best essay than you can get the MOST marks.
8. Essay in Part B and Part C is usually ONE form 4 and ONE form 5. So DON’T SPOT
QUESTION. Study all the physics concept.

A student carries out an experiment to study the relationship between the
electromotive force (e.m.f), E, and internal resistance, r, of the dry cells. The
arrangement of the apparatus for the experiment is shown in Figure 1.1

When the switch is closed, the rheostat is adjusted so that the reading of the ammeter, I
= 0.1 A. The reading of the voltmeter, V1, is shown in Figure 1.2 on page 6.
The experiment is repeated by adjusting the rheostat to obtain the readings of the
current, I = 0.20 A, 0.30 A, 0.40 A and 0.50 A . The readings of the voltmeter
(0 V- 3 V) are shown in Figure 1.3, 1.4, 1.5 and 1.6 on page 6.
When the cells are connected to a circuit, the e.m.f of the cells, E, and its internal
resistance, r, can be determined by the formula,
E = V + Ir. E = V + Ir.
