Coefficient of static friction experiment

[SwAnK]

hey I did this experiment where I dragged a mass by a scale until it moved to find the static friction. Then weight was added to the mass and the process reapeated. My question when graphed and the mass or Fn on the x-axis and the applied force or Fs on the y-axis should it not plot a straight line through 0,0, which owuld be the coeffiecent of static friction?? I am just wanting to know because either i messed up the graph or got messed up results during the experiment.
thanx for your time

Per the theory that static frictional force equals normal force times coefficient of friction, yes the line graphed should cross 0,0. The line should be straight and the slope indicates the coefficient (dy/dx).

Hello, thank you for sharing your experiment with me. The coefficient of static friction is an important factor in understanding the relationship between the applied force and the weight of the object. When graphed, it should indeed show a linear relationship with the x-intercept representing the coefficient of static friction. However, it is possible that there were errors in the experiment that could have affected your results. It is important to carefully control all variables and ensure accurate measurements in order to obtain reliable data. I would recommend reviewing your experimental procedure and data to see if there were any mistakes or sources of error that could have affected your results. Additionally, it may be helpful to repeat the experiment multiple times to ensure consistency and accuracy. I hope this helps and good luck with your future experiments!
