Austin Green Lab Partner: Clint Albrecht Conclusions Summary: The error bars decreased as the distance got longer. The U(x) decreased as the distance increased because the repulsion forces are weaker the farther the magnets are apart. My force at the end ended up to be 2.7263 +/- .0166 N and after I took my negative derivative of the slope I ended up with .0016. From this I can tell that the approximation was not exactly between the experimental uncertainties. Looking at my graph, I also noticed that the weighted least-square fit line wasn’t exactly lined up with my points, so it showed that the data was a little off. Although the line did stay pretty much within the error bars, so technically the data wasn’t too far off.

Unformatted text preview: Error Analysis: At times when releasing the glider, if it was a small distance x then you would have to hold it a different way on the release. This happened because as the magnets got too close our glider jumped to the side and off the track. There also could have been some illegitimate errors in the calculations, because of mixing up the significant figures or the units. Systematic errors can also be a possibility because of faulty equipment, calibrations, or the actual experimental design. Also, every measurement used (especially with the timers) could be subject to random error....
