Magnets: pulling and pushing without touching, sentence 14

Maglev trains use strong magnets to float above the track and move along it; with no wheels touching, there is almost no friction.

Who acts: Maglev trains, wheels, friction · What happens: use, float, move, touch, be · To what, where: strong magnets, track, magnet

This is a sentence of the lesson «Magnets: pulling and pushing without touching» 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 (Maglev trains, wheels, friction), 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): R1-cc-next ×1, 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.
