**Who acts:** wheel, heavy things, rolling · **What happens:** make, move, slide · **To what, where:** less friction

<!-- .vabout -->
This is a sentence of the lesson «Pushes, pulls, friction and wheels» of the world 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 (wheel, heavy things, rolling), what happens, when and where, as Mova's frames read it from the tree.
