So you obviously know that you have to plot the tangent functions graph using your unit circles and a table of values. Once you are done with that, you need to establish improvements/refinements to your method of getting precise measurements to craft a function that does a good job of modeling the "simple harmonic motion" of a mass suspended at the end of a spring. Think about:
(a) Number of oscillations in a given time period.
(b) The period (time taken for one oscillation).
(c) The lowest height, the greatest height and the equilibrium position.
(d) How you can utilize all the members of your group in an efficient way.
There may be other considerations and you should certainly discuss them using the blog. On Friday, without a single minute to waste, you must be ready to commence with your function modeling exercise. The end goal is that you come up with a function that fairly accurately models the motion of the suspended mass.

So has anyone found a way to find the height of the oscillations and equilibrium besides looking at the ruler as the spring is bouncing up and down? Is there an easier way?
maybe a camera replayed in slo-mo?
but we don't have a camera in class.
i see what you are saying Victoria but if you have more than one person measuring at the same time you could average their estimates to get a pretty accurate set of data
i dont know how other groups started their oscillations so feel free to tell me if i am going in the wrong direction here, but my group just pulled the mass on the spring a certain length closer to the ground than the equilibrium postition and let it oscillate from there
yeah averaging is good idea to be more accurate, but i still feel like there has to be an easier and more reliable way- i dont know
I know that if you run the experiment multiple times and then average the results of the trials together, you can get a solid, more accurate data set. So maybe if we ran the trials a few time and then averaged we could get a better set of data.
