Re: [Phys-l] [ap-physics] The Swinging Bucket Problem



Hi all=
I dispute thhe presumption that Dan's phrasing, as stated, is ``more precise'', but the posting does emphasize the need for carefully defining terms. The necessary preliminary is a sketch with the directions labeled. Whether you call the radial direction (with a bucket on a rope)
``radial'' or ''centripetal'' or ''along the rope'' or something else, is inconsequential as long as everyone is clear on your meaning.
Regards,
Jack

I regularly use the longer, but more precise, phrase "the sum of the
forces in the centripetal direction".

... which is just another argument for banishing the expression
"centripetal force" from the English language...
