If we want to build the idea of masses or charges interacting with
gravitational or electrical fields, resulting in forces, shouldn’t we
introduce fields first?
When introducing F=mg, is g the gravitational field or is it the local
"acceleration of gravity" (acceleration of an object in the local frame
when the only force acting is gravity)? In other words, does mg
include the centrifugal force associated with the rotating frame of
reference? Might this impact how you introduce the material?
