Thanks! I thought fitting meant just inserting the experimental values into the equation and solving for "k". I will look into "least squares fitting". As for solving for ##(f-kv)##, from equation (2) in the paper I linked, you can find ##f = Iα/R##. You can then insert moment of inertia for...

My goal is to find the drag coefficient so I can see the strength of the induced eddy currents acting on the magnet. It is not about learning fundementals about experiments. In the end I will write a report of some sorts about the results and the experiment. It is not a school project, something...

Thanks for the compliment! By "running the simulation", do you mean running the equation with the angle and mass to find the ideal acceleration? how do I make a range of guessed values for the drag coefficient? I don't have any basis to make an estimation for the drag coefficient. This is my...

Thanks for the reply, it cleared up a lot. I still have a few questions though. Which "messy constants" do I replace with which "neat ones". I'm not sure since I don't see any constant to replace with time or distance. I know it is very a amateurish question but I really don't have much...

Before starting, I will leave the link to the article I am talking about here: http://www.msc.univ-paris-diderot.fr/~phyexp/uploads/LaimantParesseux/aimant2.pdf I am conducting a similar experiment to the one discussed in the paper above. Basically, I am rolling a neodium supermagnet down a...
