About these units
Running Speed (run)
Human running speeds range widely: Average jogging (2.5–3.3 m/s or 9–12 km/h), Sprint speeds (8–12 m/s or 29–43 km/h). Elite sprinters can exceed 12 m/s, with Usain Bolt's peak reaching approximately 12.4 m/s. Running is biomechanically complex, involving elastic energy return, stride mechanics, ground-reaction forces, and cardiovascular performance. Sports science uses running speed to evaluate training outcomes, optimize gait, prevent injuries, and enhance athletic performance. Running speed provides a window into human physical capability and evolutionary adaptations.
Earth's Velocity (v⊕)
Earth's orbital velocity around the Sun averages about 29.78 km/s, or roughly 107,000 km/h. This enormous speed is imperceptible to us because everything on Earth—including its atmosphere—moves with the planet. Earth's velocity varies slightly over the year due to its elliptical orbit, being fastest at perihelion (closest to the Sun) and slowest at aphelion (farthest distance). This velocity influences astronomical observations, Doppler shifts in starlight, and the calibration of spacecraft navigation. Earth's motion through the Solar System is a reminder that even when we feel stationary, we are traveling at extraordinary speeds through space.
