For example, when Glynda shot the purple Dust missiles at the airship (In V1, but still, Gravity was already a thing back then), pushing it notably on impact. And to at least some extent it can replicate the effects of the barrier, by modifying gravity to provide a "Repulsion" effect, pushing things away like Weiss's barrier did to the WF mooks. The thing is that in most magic systems using them "gravity" and "force" are different magics... with gravity only pulling objects and force pushing them, while the effect can be the same the intent and expectations of what they do are slightly different.
