Understanding

Ability to translate, interpret, extrapolate and understand concept or principles in physics fields which involve the use of knowledge without new situation and do not require explanation about the implications towards the knowledge

Question (Paper 1)1. Hand scalded by steam is more painful compare to hand scalded by boiling water because A steam has a higher specific latent heat than waterB steam loses heat slower to surrounding compare to waterC steam has a higher temperature

Question (Paper 2)1. Before a football tournament, the ball to be used in the game must have a suitable pressure. Explain why a ball with less pressure is not suitable for the football tournament.[4 marks]

Suggested answer

Ball with a suitable pressure have small/ less reaction time

So the impulsive force is greater

And the ball can go further

F=(mv mu)t

Problem SolvingThe ability of using knowledge , scientific skills and thinking skills to solve physics problem qualitatively and or quantitatively. (Paper 2)The ability to solve physics problem by scientific investigation. (Paper 3)

Question (Paper 2 Section B) An earth-monitoring satellite falls into the earths atmosphere at high velocity and reaches a high temperature. This is caused by the earths gravitational force and air resistance. Using the appropriate physics concepts, suggest and explain suitable designs or ways to protect the satellite and its equipment : (i) from extreme heat (ii) from breaking up on landing

Suggested answer(i) heat resistant materials : prevent heat from entering High melting point materials : impregnable to being liquefied

(ii) low-density materials : reduce impulsive force Rigid, light and strong materials : not easily breakable and dented Fitted with a parachute : increase air resistance, reduce velocity

Question (Paper 3) Refer to Paper 3 questions

Forces and Pressure] A automotive student ordered to investigate charecteristics of liquid for using in brake hydraulic system of car. Diagram 6 shows an arrangement of hydraulic.

Table 6 shows characteristic for four type liquid that using as brake liquid above. Based on Table 6 above, describe the characteristics of liquid appropriation so that the liquid used as liquid in the apparatus above. Next select which liquid more appropriate used for this purpose.

StrategiesRefer to general strategies

The ability to reason by identifying and analysing common characteristics or variables and synthesis the common characteristic or relation with variables to create a physics concept. CONCEPTUALISATION

CONCEPTUALISATION CRITERIA - list common characteristics correctly- classify or explain common characteristic or variables correctly- relate characteristic and variables to create concept correctly with identical justification.

Question (Paper 2 Section BDiagram 1 shows :Daniel is drinking with a strawDiagram 2 shows : An empty syringe is dipped in water and the syringe piston is pulled up. From the diagrams state the identical characteristics ,explain the phenomenon and name the science concept involved Diagram 1Diagram 2

Diagram 1 water flows/ gets into the straw Diagram 2 water flows into the syringe When air molecule are sucked up, air pressure inside the straw decreases. The external pressure (atmospheric pressure ) which is higher pushes the water into the mouth / the straw.When the piston is pulled up , air pressure inside the straw decreases . External pressure (atmospheric) which is higher pushes the water into the syringe.Physics concept : atmospheric pressureSuggested answerDiagram 2Diagram 1
