1 A teacher is explaining the differences between accuracy and precision to her students.
She draws the following diagram, which shows different degrees of accuracy and
precision. The circles represent targets A, B, C and D and the dots represent arrows
hitting the targets.
,2 A student released a ping pong ball in front of a metre rule and used a phone camera to
record the motion of the ball as it fell. The phone camera captures 60 images per second,
which may be played back one image at a time.
(a) The ball was dropped from a height such that it reached its terminal velocity as it
passed the metre rule.
(i) Explain how the terminal velocity of the ball could be determined using the
phone camera recording.

, 3 A student carried out an experiment with a pendulum hung from a fixed support. The
fixed support was a distance h above floor level as shown.
fixed support
string
h
bob
d
floor
As the student was unable to measure the length of the pendulum directly, she measured
the distance d from the bob to the floor.
(a) To determine the period T of the pendulum, the student used the following method:
• release the bob from its highest position and start a stopwatch
• stop the stopwatch when the bob reaches the same position again.
Criticise the student’s method for measuring the period.
