About these units
Kilometer/Minute (km/min)
A kilometer per minute corresponds to 60 km/h per unit, making it a useful measure for high-speed trains, rockets, and conceptual velocity comparisons. It is too fast for normal transportation but too slow for astrophysical use, placing it in a niche area: intermediate high-speed phenomena. Engineers may use km/min to quickly estimate travel times or evaluate rapid mechanical processes. It offers a convenient stepping stone between km/h and km/s.
Cosmic Velocity - Second (v₂)
The second cosmic velocity is the escape velocity, the speed required to completely overcome a planet's gravitational attraction without further propulsion. For Earth, this speed is about 11.2 km/s. It is higher than v₁ because escaping gravity requires exceeding orbital balance entirely, not merely achieving stable free fall. Escape velocity underlies missions to the Moon, other planets, and deep space probes. Reaching v₂ allows spacecraft to travel along trajectories that leave Earth's gravitational well permanently unless acted on by external forces. This value symbolizes humanity's ability to break free from its home world—a critical milestone in exploration.
