About these units
Meter/Second (m/s)
The meter per second is the SI unit of speed, representing the distance traveled in meters over one second. It is the foundational unit for physics, engineering, and scientific measurement because it derives directly from SI definitions of distance and time. In physics, m/s appears everywhere: from the velocity of falling objects and planetary orbits to the propagation of waves and fluid flow. It is the preferred unit when describing speeds mathematically because it integrates cleanly with SI-based equations involving energy, force, and momentum. Although not commonly used in everyday life—where km/h or mph dominate—m/s is essential for precision. Weather forecasts, for example, often use m/s for wind speeds in scientific analyses even if the public version converts to more familiar units. The clarity and mathematical consistency of m/s make it indispensable in scientific communication.
Cosmic Velocity - Second (v₂)
The second cosmic velocity is the escape velocity, the speed required to completely overcome a planet's gravitational attraction without further propulsion. For Earth, this speed is about 11.2 km/s. It is higher than v₁ because escaping gravity requires exceeding orbital balance entirely, not merely achieving stable free fall. Escape velocity underlies missions to the Moon, other planets, and deep space probes. Reaching v₂ allows spacecraft to travel along trajectories that leave Earth's gravitational well permanently unless acted on by external forces. This value symbolizes humanity's ability to break free from its home world—a critical milestone in exploration.
