Motion

Looking Around 2 — Means of Transport / Animals. Things that move — buses, birds, fans — appear throughout transport and animal chapters.

• Motion means changing position.
• Rest = not moving; motion = moving.
• Types: straight, circular, back-and-forth.

Verbal: Motion means your position changes. Rest means staying in the same place.

Symbolic: Types: straight (car on road), circular (fan), back-and-forth (swing). Force → can start motion.
