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

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.

Pahang 2009 Section A (28 marks)

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.
