Reflections 3: Ziplock Zoomer
This week we held an investigation on the interaction of force with mass. We all had 5 quarters, a Ziplock bag, a paperclip and an apparatus. In this experiment, we first started by calibrating our devices. Then, we attached a paperclip to the bag and our force probe. We started the measurement without anything on the bag to make sure that we take into consideration the weight of the bag and paperclip on the probe. Then we proceeded to add quarters as a unit of mass. Eventually we had 6 trials and compiled our data onto LoggerPro.
The purple data represents the data unaltered with mass at 0, the force represents the weight of the paper clip and ziplock bag. The blue data represents the Adjusted force where we inputed a formula to make the force of the paperclip and the ziplock equal to zero to find the true force of the quarters. The graph below shows the Adjusted Force over Mass.
One thing to notice is how when you look at both linear fits for the unadjusted and adjusted force, the slopes are the same 0.55 N/Quarters. This goes to show that the slope is independent and unaffected by the intercept.
Hey Keisi, you described our experiment very well. You went into detail explaining how exactly we went about measuring the data to the point where an outsider may easily replicate the experiment. One difference between how you and I described the experiment is that you explained the difference between your data, mainly the Force vs. Adjusted Force. Even though your prediction isn't listed, I'm sure yours would've been similar to mine since our slopes weren't too far off. Your data is relatively unchanged since class time, therefore your perspective on how you conducted the experiment must be the same as well.
