<!-- .ven lang=en -->
On a smooth train a ball you drop lands at your feet, because the ball was already moving along with the train and you.

<!-- .vintro -->
**Who acts:** you, ball · **What happens:** drop, land, move along · **To what, where:** ball, smooth train

<!-- .vabout -->
This is a sentence of the lesson «Speed: fast and slow» of the physics course of Mova's primary school.
