Drop distance vs number of rubber bands
Aim: To test if the number of rubber bands affect the drop
distance with a 200g weight
Hypothesis: If you add more rubber bands then the drop
distance will be greater
Materials:
Weight (100g, 200g, 400g)
Rubber bands
Clamp
Retort stand
Boss head
Masking Tape
iPhone (to record)
Method:
1. Set up the apparatus with the large clamp holding the
retort stand, the boss head should be holding the clamp,
tape the tape measure to the clamp so you can measure
the drop distance.
2. Attach the 200g weight to the rubber bands and drop
from the same height every time.
3. Use iphone to record the results
4. Record results and repeat with different amount of bands.
5. Using the same setup use 2 rubber bands and change the
mass
6. Record the results for experiment
7. Make sure to do 3 trials for the most accurate result

Conclusion:
The hypothesis is supported as shown the amount of rubber
bands increase the drop distance.
Discussion:
The results for the number of bands vs drop distance is not
linear but very close due to the random errors such as
elasticity of the bands and different band knots.
The results of Mass vs Drop Distance is also non-linear but
very close with the same random errors as the other
experiment.
