# Balance: the centre of gravity, sentence 11

<!-- .ven lang=en -->
A tightrope walker's long pole is slow to turn, which gives the walker time to correct wobbles.

<!-- .vintro -->
**Who acts:** long pole · **What happens:** be, turn, give, correct · **To what, where:** wobbles

<!-- .vabout -->
This is a sentence of the lesson «Balance: the centre of gravity» 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 (long pole), what happens, when and where, as Mova's frames read it from the tree.
