By speed · Order from slowest to fastest.

1. The drift of a tectonic plate 21.9 mm/year

   Plates move about as fast as your fingernails grow, yet over millions of years they have rearranged whole continents.

2. A person jogging 10.8 km/h

   Humans are among the best endurance runners on Earth, able to outlast horses over very long distances in heat.

3. A luge slider 140 km/h

   Luge athletes steer a tiny sled with subtle leg and shoulder pressure while lying on their backs, feet first.

4. A record badminton smash 565 km/h

   The shuttlecock is the fastest object in any racket sport, though it decelerates almost as quickly as it launches.

5. The speed of sound at sea level 1.2K km/h

   Sound travels faster in warm air than cold, so a thunderclap's timing shifts slightly with the weather.

6. An F-22 Raptor at top speed 2.4K km/h

   The Raptor can supercruise, flying faster than sound without afterburners, sipping less fuel as it streaks along.
