Forces — pushes, pulls, friction and magnets, sentence 6
Rough surfaces make more friction than smooth ones: a sledge slides far on smooth ice but stops quickly on grass or gravel.
Who acts: Rough surfaces, sledge · What happens: make, slide, stop · To what, where: more friction, smooth ice, grass
This is a sentence of the lesson «Forces — pushes, pulls, friction and magnets» 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 (Rough surfaces, sledge), what happens, when and where, as Mova's frames read it from the tree.
