Systemic Error: Lost Length: While we pretended that L' was the length of the entire string, in reality, you probably had some loose at both ends, some looped over the pendulum, some wrapped in knots, and so
on. This can be quite an important systemic error, depending on your setup.
Qualitative Impact Discuss the direction of the impact of this on each part of the experiment (and state
when it would have had no impact).
• Quantitative Impact Estimate how much total length of string could have been "tied up in this way (and
remember that it's the stretched length that matters for the gold string, so take that into account when you
make that estimate). Be sure to explain how you made your estimate. How much relative error could we
have had in L
