Riding a bike: why it stays up, sentence 10
Cyclists lean into a corner to balance the sideways push of the ground on their tyres; turning sharply without leaning makes you fall outwards, and leaning hard while going very slowly tips you over inwards.
Who acts: Cyclists, turning, you, leaning, ground · What happens: lean, balance, turn, make, fall, go · To what, where: corner, sideways push, you
This is a sentence of the lesson «Riding a bike: why it stays up» 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 (Cyclists, turning, you, leaning), what happens, when and where, as Mova's frames read it from the tree.
