[QUOTE="PeterDonis, post: 5485447, member: 197831"] I'm not sure this is a matter of convention, unless you are also treating the term "weight" as a matter of convention. In the usual usage, "weight" is a force and its direction should be a direct observable, which must be describable by an invariant. "The direction the object would move if it were force-free" seems more like geodesic deviation to me. [/QUOTE]
