1. A length of string is measured between two points on a ruler.
When the length of string is wound closely around a pen, it goes round six
times.
pen six turns of string
What is the distance once round the pen?
A 2.2 cm B 2.6 cm C 13.2 cm D 15.6 cm A
2. When does an object falling vertically through the air reach terminal velocity?
A when the acceleration of the object becomes negative
B when the acceleration of the object is equal to g
C when the air resistance equals the weight of the object
D when the air resistance is greater than the weight of the object C
3. An athlete runs a 100 m race in a straight line. The table shows how his speed
changes with time for the first 5.0 s of the race.
speed m / s 0 1.7 4.1 5.7 6.5 6.8
time / s 0 1.0 2.0 3.0 4.0 5.0
What is the average acceleration of the athlete between time 2.0 s and time
3.0 s?
A 1.6 m / s2
B 1.9 m / s2
C 4.9 m / s2
D 5.7 m / s2 A

An astronaut has a mass of 75 kg.
What is the weight of the astronaut on the Moon?
A 47 N B 75 N C 120 N D 740 N C
5. Two objects P and Q are placed in a beaker containing a liquid.
Object P floats in the liquid and object Q sinks.
Which row for the densities of object P, object Q and the liquid is possible?
density of object P density of object Q density of liquid
g / cm 3 g / cm 3 g / cm 3
A 1.2 0.6 0.8
B 1.2 1.4 1.0
C 11.3 8.9 13.6
D 11.3 19.3 13.6
D
6. A ball of mass 0.12 kg is hit by a tennis player.
The velocity of the ball changes from 0 m / s to 5.0 m / s in 0.60 s.
What is the average resultant force acting on the ball while it is being hit?
A 1.0 N B 2.5 N C 3.6 N D 8.3 N A
7. A balloon and a mass are attached to a rod that is pivoted at a fixed point P.
The balloon is filled with helium, which is a gas that is less dense than air.
The balloon filled with helium applies an upward force on the rod.
