1. Which of the following is a vector quantity?
a. Distance
b. Speed
c. Velocity
d. Work done
Answer
 C because velocity has magnitude and direction
 A is wrong because it is a scalar quantity
 B is wrong because it is a scalar quantity
 D is wrong because it is a scalar product of two vector quantities

2. Which of the following is the unit of upthrust?
a. Nm−2
b. Nm−1
c. Nm
d. N
Answer
 D because upthrust is a force

3. When a force is applied across the ends of a sample of wire, the wire extends until it fractures. The
force-extension graph for the sample of wire is shown.




A force F is applied to an identical sample of the wire and then removed.
If the sample of wire is to return to its original length, what is the maximum force that can
be applied?
a. W
b. X
c. Y
d. Z
Answer
 C because Y is the elastic limit above the elastic limit the wire will not return to shape
 A is wrong because W is the force required to fracture the wire
 B is wrong because X is the yield point
 D is wrong because Z is the limit of proportionality

4. A small stone of mass m is dropped into a pond and accelerates downwards with an acceleration a.
The free-body force diagram for the stone is shown.




Which of the following equations is correct for the stone?
a. U + D – mg = 0
b. U + D – mg = ma
c. mg – U − D = 0
d. mg – U − D = ma
Answer
 D because in the statement it said that the object will accelerate downwards hence there should be a
resultant force downwards so mg should be greater than both upthrust and drag
 Resultant force = mass x acceleration
 Resultant force = Mg – U – D
 Mg – U – D = ma

5. A student throws a ball vertically upwards and catches it after 4 s. The student’s data is used to plot a
velocity-time graph for the ball.




I. Using the graph, what is the acceleration of the ball?
a. 7.5 m s−2
b. −7.5 m s−2
c. 3.8 m s−2
d. −3.8 m s−2
Answer
 B because it is the gradient of the line
 Gradient = (0 – 15)/ (2 – 0)= -7.5 m s-2
