Who acts: car · What happens: need · To what, where: braking distance, speed
This is a sentence of the lesson «Speed: fast and slow» 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 (car), what happens, when and where, as Mova's frames read it from the tree.
