A group of students performing the Newton's Second Law experiment generated the graph shown below from their data.

hanging weight vs acceleration plot

Explain whether or not you would trust any conclusions obtained from this data. When formulating your answer, consider whether or not the effects of friction could account for the results these students obtained. What could the students have done wrong? (Hint: See the first few steps of the experimental procedure.) Explain how making this mistake could give the above results.

Trust depends on the EXACT conclusion that you make. You haven't provided the experiment nor your conclusion.It is clear from the graph that a is not proportional to m. If m is supposed to represent Force ( F= mg) then you must conclude that F is NOT equal to ma. There is no mistake in the experiment. But the results might be misinterpreted.

Now even if you consider that some mass may be present as well as the added hanging mass you get a = dF/dm = 1/1.88 ~= 0.53 This could not represent the acceleration of gravity so we are left wondering WHAT has been accelerated. Why not tell us all that missing information?
