Atwood's Machine (Help with Lab Report Conclusion)

  • #1
All that's left to write in my lab report is the conclusion, and I'm failing to understand what my professor is requesting of me. In the guidelines it says,

"Compare your measurements to the expected values. State and discuss whether
your results are in agreement with the expected theoretical value. If the value of your
percentage error (percentage difference) is smaller than the value of your experimental
error, then your results are in agreement with the theoretical value within the limits of
experimental error. If the value of your percentage error (percentage difference) is much larger than the value of your experimental error, then you must describe the reason for this. State the possible sources of error and describe the expected impact of each of these errors on your experimental results."

When he refers to percent error I know what it is he's talking about, but what is experimental error? Does he mean percent uncertainty? Because I know that % Uncertainty ≥ % Error; or at least it should.

I think you repeated your measurement and got an average and standard deviation from the data?
