EXPERIMENT 3
AIM
To
find out the relationship between different number of feather with the distance
travelled by the shuttlecock
HYPOTHESIS
The
more the number of feathers the shorter the distance it travelled
APPARATUS
24
feathered shuttlecock, 16 feathered shuttlecock, 8 feathered shuttlecock,
measuring tape, shuttle-push shooter
VARIABLES
MANIPULATED VARIABLE : Number of feathers
RESPONDING VARIABLE : Distance it travelled
CONSTANT VARIABLE : Type of feather
PROCEDURES
1. A shuttlecock shooter was set up.
2. Shuttlecocks were prepared with different number of
feather
a. 8
b. 16
c. 24
3. 8 feathered shuttlecocks was dip into colour-powder.
4. 8 feathered shuttlecocks was shot three times to take
the average reading in a close room to avoid wind factor.
5. The distance travelled by the shuttlecocks was
measured by using measuring tape.
6. The procedures 1 until 5 repeated with 16 feathered
shuttlecock and 24 feathered shuttlecock.
7. Data was recorded.

DISSCUSIONS
We found that 8 feathered shuttlecock traveled
1.36m.While 16 feathers travelled 1.39m.and 24 feathered shuttlecock travelled
1.33m.This shows that less feather shuttlecock travel longer compare to others.
This is because shuttlecock with less feather travel in less air resistance and
less frictional force. This will help the shuttlecock to travel further. On the
other hand 24 feather shuttle cock travelled in a shorter distance. This is
because there are more feathers in a shuttlecock which faced more air resistance
and more frictional force. Finally it is proved that 16 feathered shuttlecock
was able to travel in suitble distance.
CONCLUSION
The
more the number of feathers the shorter the distance it travelled.
