Description

First Cosmic Velocity (v1) – Orbital Threshold

The first cosmic velocity, about 7900 m/s, is the minimum speed an object must reach to maintain a stable orbit around the Earth without additional propulsion. This velocity is foundational in satellite launches and orbital mechanics, marking the beginning of sustained space travel.

Kilometer per Hour (km/h) in Daily Use

Kilometer per hour (km/h) is a common unit for measuring speed, especially in countries using the metric system. It denotes the number of kilometers traveled in one hour. This unit is prevalent in transportation, with speed limits and vehicle speeds often expressed in km/h. For instance, a car traveling at 100 km/h covers 100 kilometers in one hour.
