About these units
Mile/Minute (mi/min)
A mile per minute corresponds to 60 miles per hour, making it a bridge between mph and high-speed conceptual measures. Aircraft climb rates, emergency vehicle response metrics, and theoretical speed comparisons sometimes use mi/min for rapid mental calculations. The unit is also used historically in railway performance, where achieving "a mile a minute" once symbolized extraordinary locomotive speed. Today it stands as both a technical unit and a romantic benchmark of transportation history.
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.
