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

Observe the reading perpendicular to the eyes 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

Questions no 1

a. Manometer measurement (pressure and height) (MRSM 2008)

b. Protractor (Refraction)

c. Interferens (measure distance of separation)(DIAGNOSTIK KL 2010)

Questions 2 (Graph)

a. Light of lenses (f

1=

v

1 +

u

1 )

b. Internal resistance ( negative graph)

c. Refractive index (sin i vs sin r)

Questions 3 (Form 4)

a. Pressure with height (measurement with manometer – u Tube, thristle funnel)

b. To investigate the relationship between the pressure and the temperature ( Pressure

law’s- Bourdon gauge and thermometer)

c. To investigate the relationship between the sine of incident angle ,i and the sine of

refracted angle, r

Questions 4 (form 5)

a. To investigate the relationship between the distance between two sources and

distance between two separation, a α x

1

b. To investigate the relationship between the area cross sectional of the wire, A ,

(length ) and the resistance, R of the wire

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 TOP Discussion Topic

1. Inertia (4 marks)

2. Pressure due to height (5 marks)

3. Momentum (6 marks)

4. Electromagnetic induction (Transformer ) (7 marks)

5. Elasticity (8 marks)

6. Resistance and area cross sectional (8 marks)

7. Gas Law (10 marks)

8. Electronic ---Transistor (12 marks)

9. Bernoulli’ s (12 marks)

10. Archimedes Principle (12 marks)

11. Radioactive (fusion and Fission) (12 marks)

12. Heat (Charles Law’s) Light (Lenses) (12 marks)

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.

4 Diagram 4.1 and 4.2 shows the electric circuit consist with an electric bells, switch and battery. When the switch is closed, it is observes that the bell in Diagram 4.2 rings louder than the bell in Diagram 4.1. Both electric bells in each diagram are same.

Rajah 4.1 dan 4.2 menunjukkan litar elektrik mengandungi satu loceng elektrik, suis dan sel kering. Apabila suis ditutup, didapati loceng dalam Rajah 4.2 berdering lebih kuat daripada loceng dalam Rajah 4.1. Kedua-dua loceng adalah sama bagi setiap rajah.
