PHYSICS Workshop 2018
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 www.guruthong.wordpress.com
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.

Diagram 3 shows two similar coffee maker A and B, containing different amount of
coffee on similar hot plates stove. The coffee in both coffee makers are heated by
turning on the power supply of the hot plate. After few minutes, it was observed that
the coffee in coffee maker B is hotter than the coffee in coffee maker A.
Rajah 3 menunjukkan dua pembancuh kopi serupa A dan B, mengandungi jumlah
