Spring Constant and Time Period

  1. Feb 19, 2012 #1

    I am investigating the effect of changing the spring constant on the time period of Simple Harmonic Oscillations.

    My first doubt regards one of my control variables. I listed that I should try and maintain air humidity constant, due to the fact it affects air resistance and, therefore damping. Obviously, I don't have absolute control over the humidity in the air but how could I try to maintain it constant? Maintaining the relative humidity the same

    Any ideas?

    Not that you would actually do this in an introductory physics lab, but probably the easiest way to control the humidity is to keep it at or close to either 0% or 100%; maintaining it somewhere in between would be very tricky. See if you can think of ways that holding it at either 0 or 100% might be done.
