Who acts: object, weight, one point · What happens: act, sit, call · To what, where: one point, centre · Speech: someone speaks here
This is a sentence of the lesson «Balance: the centre of gravity» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (object, weight, one point), what happens, when and where, as Mova's frames read it from the tree.
