Rockets, record speeds and motion everywhere, sentence 7

To circle the Earth, a rocket must move at about 28,000 kilometres an hour sideways; at that speed it falls round the Earth instead of back down.

Who acts: rocket · What happens: circle, move, fall · To what, where: Earth, 28,000 kilometres, speed

This is a sentence of the lesson «Rockets, record speeds and motion everywhere» 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 (rocket), 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 ×1, R7-rel-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.
