About these units
Speed of Sound in Pure Water (vₕ₂ₒ)
The speed of sound in pure water is approximately 1,480 m/s at room temperature, though it varies with temperature and pressure. Sound travels faster in water than in air because water molecules are more tightly packed, allowing vibrations to propagate more efficiently. This speed is critical for sonar systems, underwater communication, acoustic research, and marine biology. Whales, dolphins, and submarines all rely on sound propagation through water, where visibility is extremely limited. Understanding vₕ₂ₒ allows accurate modeling of ocean acoustics, ranging from climate studies to naval operations.
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.
