Experimental accuracy – if experiment 1 were repeated with 100g weights instead of 50

12

Experimental accuracy – if experiment 1 were repeated with 100g weights instead of 500g weights, would the results be less or more accurate? Why?
The aim of this lab is to calculate and predict the loading and reaction forces required to keep a real-life system in static equilibrium
im measuring the force not mass.
would this be the answer?
According to the results from experiment 1 and by comparing between thetheoretical and measured results for both 500g and 100g, it has been shownthat using the 100g weights gave out more accurate results. This clears out thatusing less weights produces more accurate results. This could be because theweights we used were just 10g, and using a large amount of them could causean increase in the errors or uncertainties giving out less accurate results.
so this is the valid answer

Let's determine whether it is valid to use a 100-gram weight to test static balance. They are much better than those heavy 500-gram weights. Above all, lighter weights reduce errors, ensuring more reliable data. Last but not least, using only 100-gram weights prevents the accumulation of uncertainties arising from the use of various lower weights, for example 50 -gram. It also keeps the forces within the optimal range of your equipment, making your studies more accurate when trying to determine static balance.

I arrived at my answer by considering the benefits and drawbacks of using a 100-gram weight, compared to using 50-gram or 500-gram weights.
My method included:
-Clearly defining the objective and limitations.
-Comparing the 100-gram option to the 500-gram alternative.
-Comparing the 100-gram option to lighter ones, like 50-gram weights.
I also used error propagation, stack-up analysis, and signal-to-noise ratio principles.
