Measuring quantity 1
Measure the original length of the fishing line (approx. 0.6m) using a one metre ruler, since we are using a one metre the uncertainty of our measurement using an one metre ruler would be ±0.5m and in addition, the smallest resolution on an one metre ruler is ±0.0005m therefore the overall uncertainty is (±0.0005m/ ±0.5m) x100 is 0.1% which is acceptable for this experiment.

Measuring quantity 2
I will measure the diameter of the fishing line using a digital calliper, the digital calliper has a uncertainty of ±0.000005m and I predict that the diameter of the fishing would be 0.1mm (±0.001m) therefore the overall uncertainty would ±0.000005/±0.001m x100 is 0.5% which is acceptable for our experiment.

Measuring techniques
When measuring the diameter fishing line using a digital calliper, measure the diameter of the fishing line at 3 different orientations at 10cm, 20cm, 30cm and 40cm to find the average diameter.
Also when measuring the original length, measure the length with the mass holder therefore the fishing line would be straight to get a more average value. When measuring the fishing line, make sure you measure at eye level to avoid parallax error.

Repeatability
Make sure when you remove the masses from mass holder see if the fishing wire hasn’t undergone plastic deformation, if it has not undergone plastic deformation repeat the values again at least twice if the values are not close together repeat a third time to
