We've been promoting the concept of perimeter weighted golf balls for years now as a means to reduce overall spin off the tee and significantly reduce the sidespin that leads to errant shots (hooks and slices). This is a great video that shows why the distribution of weight is so impactful! thanks Chad!
A complicated concept made simple. I used this video today in my high school physics, distance learning lesson about the conservation of angular momentum. Thanks for posting it.
Video from a few months back, but I only uploaded it today, because I need it for class. Demonstrating angular momentum conservation at the playground, with an assist from SteelyKid. (I previously did something similar with her on the merry-go-round, seen here: ua-cam.com/video/ih0--3ShN2U/v-deo.html But the effect is more dramatic with my fat ass up there spinning...)
My high school physics class did this with an office chair and some hand weights filched from the gym. It was oddly liberating, after 16 years of constantly being told DON'T SPIN ON THE CHAIR!
Yeah, in the majors classes we do a version with a rotating platform and hand weights. The first year I did it, I got so dizzy I had to babble for a bit to cover the fact that I couldn't read the writing on my slides. (There's an out-take from the above video where SteelyKid spun the merry-go-round so fast that I couldn't drag myself all the way to the center against the centrifugal force... That took some recovery before we shot the final version...) I always do it myself, because when I was at Yale, one of the profs there picked a student volunteer to be the one spinning. When she kicked off to get herself going, she started spinning too fast, so when she pulled her arms in, she lost her balance, and hit her head on the lab table and bled all over the room... Sadly, the demo platform is too heavy to drag over to the building where I'm teaching this term.

Showed this to Hulda. She promptly peppered me with physics about how it worked, and digged SteelyKid's role.
