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.
Meter/Hour (m/h)
A meter per hour is an extremely slow speed, corresponding to the distance of a single meter traveled over a 60-minute period. This unit is rarely encountered in daily life but is useful in engineering contexts where mechanical motion is very slow—such as conveyor systems, slow-moving robotics, geological creep, or precision laboratory instruments. Environmental sciences also use m/h to describe gradual natural processes like glacier movement or soil displacement. The unit highlights the diversity of real-world velocities—from near-light-speed phenomena to movements almost imperceptibly slow.
