**Who acts:** falling apple, gravity · **What happens:** fall, speed up, keep, pull · **To what, where:** gravity

<!-- .vabout -->
This is a sentence of the lesson «Why things fall: the apple and the pull of the Earth» 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 (falling apple, gravity), 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): R5-strong ×2, R8-pos-agree ×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.
