Lab Parts: Evaluating Spring Constants with the Least Squares Method of Data Fitting

Student Researched Lab Experiment to evaluate Spring Constants Introduction In this experiment we evaluated Hooke’s law by measuring the stretch of a spring with incremental masses. A motion detector provided position measurements and the masses were added 100 grams at a time. To calculate the spring constant we utilized the least squares method of data fitting on a Force by distance graph. Samples Calculations Line of Best Fit: f(x) = 0.202x + 16.5 xi-mean height, yi-force of gravity (1) Mean […]
