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

Sample Paper 3

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

FIGURE 1.1 /RAJAH 1.1

A ray of light is directed along the angle of incidence, i = 20o and forms the angle

of refraction, r. The angle of refraction is measured by using a protractor. The

corresponding reading of r1 , is shown in Figure 1.2 on page 5.

The experiment is repeated by varying the angle of incidence, i, to 30o, 40o, 50o

and 60o. The corresponding angles of refraction, r are shown in Figures 1.3, 1.4,

1.5 and 1.6 on pages 6 and 7 respectively.

Paper 3 Part B

Diagram 3.1 shows a worker pushing down on the piston of a clogged bicycle pump. Diagram 3.2 shows

the same worker finding it harder to push the piston further down.

With the use of apparatus such as a Bourdon gauge and other apparatus, describe an experiment to

investigate the hypothesis stated.

4. Diagram 4.1 show a lamp which lights up with normal brightness when the dimmer knob is set at its

minimum value. Diagram 4.2 shows the lamp dimmer when the dimmer knob is set at its maximum

value.

With the use of apparatus such as constantan wire, voltmeter and other apparatus, describe an

experiment to investigate the hypothesis stated.
