SECTION A
You should spend a maximum of 20 minutes on this section.
Write your answer to each question in the box provided.
Question 1
A car travels 9000 m in 90 seconds. What is the car's speed?
Use the equation: average speed = distance travelled / time taken
A B C D
0.01 m/s 0.1 m/s 10 m/s 100 m/s
Your answer: [ ] [1]
Question 2
A lift is stationary 20 m above the ground. The lift moves upwards until it is now 100 m above
the ground. The lift then remains stationary. The mass of the lift is 450 kg. What is
the increase in gravitational potential energy of the lift?
Gravitational field strength = 10 N/kg
Use the equation: gravitational potential energy = mass × gravitational field strength × height

Your answer: [ ] [1]
,Question 3
A mobile phone is charged for 3 hours. The mean charging current is 0.15 A. What is the charge
transferred to the mobile phone in this time?
Use the equation: charge flow = current × time
A B C D
0.45 C 27 C 540 C 1620 C
Your answer: [ ] [1]
Question 4
The graph shows the results for two springs, Spring X and Spring Y, as they are stretched.
(Graph: Force (N) vs Extension (cm). Spring X: straight line through origin. Spring Y: curved line,
steep at start then flattening.)
Which observation is correct?
From 0 cm to 2 cm extension From 0 N to 10 N force
A Spring X requires less force to stretch than Spring Y Spring Y obeys Hooke's Law
B Spring X requires less force to stretch than Spring Y Spring Y does not obey Hooke's Law
C Spring X requires more force to stretch than Spring Y Spring Y obeys Hooke's Law
D Spring X requires more force to stretch than Spring Y Spring Y does not obey Hooke's Law
Your answer: [ ] [1]
, Question 5
A 2 V power supply is connected to a motor. 250 C of charge passes in 50 s. How much energy is
transferred?
Use the equation: energy transferred = charge × potential difference
A B C D
5J 100 J 125 J 500 J
Your answer: [ ] [1]
Question 6
A student uses a stopwatch to measure the time it takes for a marble to travel down a ramp
between two markers. Which change will make the results more accurate?
A B C D
Asking a second Decreasing the Moving the Starting the stopwatch
student to operate height of the markers closer as soon as the marble is
the stopwatch ramp together released
Your answer: [ ] [1]
Question 7
A spring stores 100 J of elastic energy when it has an extension of 8 cm. Its extension is reduced
to 4 cm. What is the elastic energy now stored?
Use the equation: energy transferred in stretching = ½ × spring constant × (extension)²
