<!-- .vintro -->
**Who acts:** Using, heat · **What happens:** use, mean, turn, spread out, be · **To what, where:** energy, useful energy, heat · **Speech:** someone speaks here

<!-- .vabout -->
This is a sentence of the lesson «Energy: what makes things happen» 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 (Using, heat), what happens, when and where, as Mova's frames read it from the tree.
