About these units
Millimeter/Minute (mm/min)
A millimeter per minute is a slow mechanical speed often encountered in CNC machining, automated laboratory equipment, and controlled industrial processes. In medicine, infusion pumps, surgical robotics, and controlled incisions may specify movement in mm/min to maintain safety and precision. By using millimeters instead of centimeters or meters, the unit ensures fine control in delicate operations where even small deviations matter.
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.
