Okay, so this is the website: <Moderator's note: link deleted as it is not a valid reference>
I found this page as I was looking for a way to compare the assumed gravitational constant of the moon and the acceleration of the hammer/feather from the Apollo 15 experiment video. I have only taken level 1 physics as an undergrad (last semester, none in HS), but there seem to be some problems dealing with the author's assumptions regarding how density works and whether a pitcher of water is a valid "low gravity environment." A quick free-body diagram seems to be helpful, but I am less than confident in my physics abilities. Therefore, I have two quick questions:
1-What seems to be problematic with this experiment to you (O, thou who doth possesses a grander mind than mine own). I hope to test the strength of my intuition and initial guesses with the help of some more highly educated person(s).
and
2-Why does the author feel this breaks Newtonian physics? I took a brief look at the blog/site, and the author seems to be trying to enlighten me and the world; my attention span, however, is not great enough to maintain focus with the temptation of better websites (e.g., physicsforums.com), so I failed to see the point.
Here's hoping I'm not asking anything too silly, and that I'm posting this in the right place. Please forgive me for any glaring or obvious errors. Cheers!
