Description

Mach – The Speed of Sound

Mach is a dimensionless unit representing the ratio of an object's speed to the speed of sound in a given medium, typically air at sea level and 20°C. Mach 1 is equivalent to approximately 343.6 m/s under these conditions. It's commonly used in aerodynamics and aerospace industries to describe supersonic speeds, such as those achieved by fighter jets and spacecraft.

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.
