QUESTION 1 MULTIPLE CHOICE
Answer these questions on the multiple-choice Answer Sheet on the inside front cover
of your Answer Book. Make a cross (X) in the box corresponding to the letter that
you consider to be correct.
1.1 Which set of physical quantities consists only of scalar quantities?
A Velocity, speed and time.
B Displacement, velocity and acceleration.
C Time, distance and speed.
D Acceleration, speed and distance.
1.2 A car is travelling west at 12 m⋅s–1 when the driver notices a stop sign. The driver
applies brakes, and the car stops at the stop sign. Which is the best description of
the velocity and acceleration of the car while it is slowing down?
Velocity (m⋅s–1) Acceleration (m⋅s–2)
A East East
B West East
C East West
D West West
1.3 A small aeroplane starting from rest can achieve a high enough speed to take off
from a runway that is 400 m long. Another, heavily loaded aeroplane, also starting
from rest, has the same acceleration but needs to achieve twice the speed to take
off. What is the minimum length of runway that will be needed for the heavy plane
to take off?
A 400 m
B 800 m
C 1 200 m
D 1 600 m
1.4 A block is suspended by a single, vertical string from the ceiling. Which force
forms a 'Newton's third law pair' with the weight of the block?
A The gravitational force exerted by the block on the Earth.
B The force from the ceiling acting on the block.
C The weight of the block has no 'Newton's third law pair' as the block is in
equilibrium.
D The force of tension in the string acting on the block.

collision?

1.6 A roller coaster starts from rest and rolls down a frictionless track, reaching speed v
at the bottom of the track. If you want the roller coaster to have a speed 2v at the
bottom of the track, what must you do to the track?
A Make the track 2 times higher.
B Keep the height the same, but make the track twice as steep.
C Make the track 4 times higher.
D Make the track 2 times higher.
1.7 Which one of the planets depicted will have the greatest free-fall acceleration on
the surface of the planet?
1.8 Two charges of equal magnitude are placed as shown in the diagrams below. In
which diagram does the resultant electric field at the dot have the largest
magnitude?
A ⊕ • B ⊕ • ⊕
C ⊕ • D •

1.10 A metal ring lies on a table. When the south pole of a magnet moves down towards
the ring, a current is induced. When viewed from above, the direction of the
induced current is:
A clockwise because the flux is increasing.
B clockwise because the flux is decreasing.
