I'm confused on part of an AP Physics lab on "Simple Harmonic Motion from a Force Perspective." Using a hanging spring & mass, motion detector, and CBL unit/Ti-83 graphing calculator, we used the calculator's graphs to create equations that included the amplitude, angular frequency, the phase offset -- y(t)= Acos(wt + symbol for phase offset). One follow-up question is how each parameter (amplitude, angular frequency, and phase offset) would change if you repeated the experiment using a larger amplitude.(adsbygoogle = window.adsbygoogle || []).push({});

Obviously, the amplitude would change. But what about angular frequency-- do amplitude and angular frequency have any sort of relationship? I've looked at all the equations I've been given in this chapter (such as w= square root (k/m) ) and all the equations relating angular frequency to period, but can't seem to find anything. Can anyone give me a nudge in the right direction here? I'd really appreciate it. :-)

Also, would changing the mass hanging off the end of the spring affect the amplitude? I realize it would change the angular frequency because of the above equation, but... Again, I feel really stupid but I can't seem to find the relationship-- any slight nudges would be very much appreciated!! :-)
