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 Number of bands Mass Trial 1 Trial 2 Trial 3 Average 2 2 2 100g 200g 400g 43 59 82 44 58 85 45 60 90 44 59 85.6 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.
