MOST COMMON PHYSICS’ QUESTIONS ASKED

The most common questions been asked in Physics Question Paper 2 are in the area of:

1. CalculationsExamples:

• Calculate the wave length of this sound wave• Calculate the critical angle of the glass prism• Calculate the final velocity of the mirror before it touches the surface of the floor• Calculate the temperature of the hot oil?• Calculate the work done by the student

2. LabelingExmples:

• Name the optical instrument P• Mark the water level in U tube• Name Instrument Q• Name the logic gate in the diagram • Name the principle involved

– State the principle involve• State function of R

3. JustificationExmples:

• Which ammeter is more sensitive• Which is the most suitable method to hang the mirror• State one reason

4. RelationshipExmples:

• State the Physical change in the mercury when the temperature increases• Relate the speed of the air to the pressure of the air• State the relationship between the energy gained by the iron ball and the distance

of projection• When the frequency is increased, what will happen to the distance between two

adjacent rows where loud sounds are heard?• State the relationship between the resistance and the intensity of light received by

the light dependent resistor?

5. Compare and contrastExamples:

• What is the difference in thelengths of the mercury coloumns at 0oC and 100oC• Compare the distance of the hand movement to throw the iron ball• Compare the air pressure above abd below the paper when air is blown • Compare the work done by the student between the two throwing techniques

6. ExplainExample

• Explain how the circuit function.(electronic circuit for the control system of lift door)

7. DrawingExamples

• Draw the logic gate symbol • Draw a diagram of triangle forces• Draw the scale drawings of the triangles of forces to determine the value of T1

and T2
