There are more than 2 kinds, but perhaps you refer to molar (M) and molal (m). Or maybe you refer to weigh/volume and weight/weight. Or, maybe even you refer to % by mass and % by volume. And there are still others.
The two kinds of verbs are action or transitive verbs and linking or intransitive verbs. Action verbs refer to verbs with an object denoting physical action while linking verbs are verbs without an object and only linking the subject with the predicate.
