About these units
Yard/Minute (yd/min)
A yard per minute is used in sports coaching, physical training, and some industrial processes. Coaches may track a swimmer's or runner's speed informally using yards per minute, especially in regions where yard-based pools or tracks still exist. Certain fabric and material-feed systems also use yd/min to specify production speed, as textiles and printing industries historically measured length in yards. The unit bridges athletic training and industrial applications in imperial-unit contexts.
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.
