We study a spring mass system with a spring attached to a horizontal rod on a ring stand and a Vernier Motion Detector under the mass to capture its displacement from a static equilibrium value at time intervals of 0.02 seconds over a time interval of about 30 seconds.
The motion detector is turned on and the spring is stretched downward and released. We collect the data and ignore (edit out) data from hand placement until a reasonable point in the motion when the oscillation is clear and clean. That cleaned up data is moved to an Excel spreadsheet and a Mathematica notebook. The apparatus with the mass has an additional resistance material in the form of taped index cars on the mass. Thus the 200 g mass with index cards taped to its base to offer more resistance makes for a total mass of 200.20626 g.
