Day 96: The Giant Merry-Go-Round-Of-Physics

Advanced Physics:

As I explained on Thursday, the students completed a short circular motion force diagram assessment:

Today, after we discussed the possible solutions (depending on how the system was defined) we talked about how nice it would be if we really ha such a thing… like a giant merry-go-round-of physics instead of the mini-merry-go-rounds (ie record players we have been using with our experiments). Well…. we do:


SIDEBAR:  I apologize for the video quality, I tried to use the ‘blur faces’ feature of YouTube, but it’s a bit difficult to blur as they ride the circular path.


The original idea and design details were shared at one of our Phox Valley Physics and Physical Science Share Meeting (many years ago) by a former member who no longer teaches in the region. As you can see in the clip, we also use a Vernier Lab Quest 2 to measure the radial acceleration.  It is configured to measure on the x-axis acceleration.   We also have the student play catch as the ride (shown in the second part of the clip) and shoot some baskets.  This was all we had time for today; you guessed it, another early release day with only 30 minute classes.
