2.1.8 Acceleration of Free Fall Experiment – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
A graph of h against t2 for a falling ball has a gradient equal to
g
g2
2g
½g
2.
A ball falls 0.80 m from rest. Taking g = 9.8 m s-2, the fall time is
0.16 s
0.40 s
0.64 s
0.82 s
3.
A systematic error from air resistance would make the measured value of g
smaller than 9.8
larger than 9.8
equal to 9.8
random
4.
Which plot of light-gate data gives a straight line with gradient 2g?
v against h
v against t2
h against v
v2 against h
5.
Why is a small dense steel ball better than a table-tennis ball?
it falls slower
air resistance has less effect
it has a smaller mass
it needs no timer
6.
The timing uncertainty counts twice in the uncertainty of g because
t is measured with a stopwatch
h has no uncertainty
g = 2h / t2 contains t squared
2 is a constant
