This is an exercise in data handling, uncertainty propagation, graphical plotting and finding the uncertainty of a gradient.
The purpose is walk students through the process of analysing data and concluding with a result and absolute uncertainty on their value for g.
The error bars come out quite large so as to show a clear example of a ‘worst line of best fit’ within the error bars.
This took my yr 13s a full lesson, with intermittent interventions from myself.
Students enjoyed the task and their confidence with data handling has moved forward as a result.
An worked solution has been included and ppt is included. Uncertainties given to 1 sig fig as is the norm.
