About these units
Cosmic Velocity - First (v₁)
The first cosmic velocity is the minimum horizontal speed an object must achieve to enter a stable orbit around a planetary body without additional propulsion. For Earth, this value is about 7.9 km/s. At this speed, an object's forward motion precisely balances with the gravitational pull downward, creating continuous free-fall—the essence of orbital motion. This velocity is foundational in orbital mechanics. Spacecraft reaching Low Earth Orbit (LEO) must achieve at least this horizontal speed, even if their vertical ascent profile varies. Understanding v₁ was essential in the early space age: it represented the threshold between atmospheric flight and true spaceflight, marking human entry into the orbital era.
Yard/Hour (yd/h)
A yard per hour is extremely slow and used only in rare cases where long-term monitoring of tiny movements is necessary—such as soil settlement in construction sites, creeping machinery, or long-term structural drift. Because the yard is an everyday imperial unit, yd/h sometimes appears in engineering logs or legacy datasets, though it is largely replaced by ft/h or mm/h in modern practice. Its use reflects the persistence of imperial measurements in certain specialized contexts.
