# Test 6 · ★ · Pushes, pulls, friction and wheels

<!-- .ven lang=en -->
A truck and a bicycle are moving at the same speed. Which needs a bigger force to stop?

<!-- .vintro -->
**Mova's choice:** option 1 · **The right answer:** option 3 · wrong ✗ · **Who acts:** truck · **What happens:** move, need, stop · **To what, where:** same speed, bigger force

This is test 6 · ★ of lesson 85 «Pushes, pulls, friction and wheels» of the world course of Mova's primary school. The page gives the question's syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause, then the 4 options as the student saw them, each with its tree and pragmatics. Every text is parsed by Mova itself.
