<!-- .vintro -->
**Who acts:** gravity, sideways speed · **What happens:** hold, keep, fall · **To what, where:** Earth, gravity, Sun.

<!-- .vabout -->
This is a sentence of the lesson «The Moon, the planets and the pull that holds them» 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 (gravity, sideways speed), what happens, when and where, as Mova's frames read it from the tree.
