Speed

you are sitting perfectly still at two million km/h.

stack every motion you’re already making and watch the number climb

Add up every motion your body is already making without lifting a finger — Earth’s spin, its orbit around the sun, the sun’s loop through the galaxy, the galaxy’s fall toward Andromeda — and the total passes two million kilometers an hour while you sit dead still. Stillness was only ever relative to the ground; pick a bigger frame and it vanishes.

Concepts: relativity, motion.
