True, but I am thinking of instances when (from a calculations and signs perspective) the sign on a frictional force can be positive; example- an object sliding down a ramp toward cartesian negative, where Fgx is negative and the net acceleration is negative, but the friction is in opposition...

Aha! That's the piece I was missing! I've actually done that, but I thought it was a cheat (and so did my students). Excellent, all is better now. Thanks!

Oiy. It is my 6th year teaching physics and early on, I diverged from the textbook (Holt Modern Physics) regarding how they handled "g". To me, it made more sense that "g" was -9.81m/s2 , while the text handled it as "g" = 9.81 m/s2, and negatives are assigned directionally. Overall, my...

Hello. I teach high school physics in a (relatively) small rural school in northeast Ohio (we are the Appalachian edge of the midwestern US). My BS is in biology with a chem minor and I worked in environmental resource planning for a number of years before going back to get a masters in...
