# Speed: fast and slow, sentence 4

<!-- .ven lang=en -->
A fast car carries much more energy than a slow one, so it needs a much longer way to stop, and that is why the speed limit outside a school is low.

<!-- .vintro -->
**Who acts:** fast car, car, that, speed limit · **What happens:** carry, need, stop, be · **To what, where:** more energy, longer way

<!-- .vabout -->
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 (fast car, car, that, speed limit), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R3-conj-first ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
