Feet per Second to Second Cosmic Velocity Conversion
Converting Feet per Second (ft/s) to Second Cosmic Velocity (v2) is a common speed conversion. 1 ft/s equals 0.000027 v2. For example, 100 ft/s is equal to 0.002721 v2.
Quick Reference Values
1 ft/s = 0.000027 v2. 5 ft/s = 0.000136 v2. 10 ft/s = 0.000272 v2. 25 ft/s = 0.00068 v2. 50 ft/s = 0.001361 v2. 100 ft/s = 0.002721 v2.
What is Feet per Second?
Feet per Second (ft/s) is a unit of speed. Feet-per-second measures speed as feet traveled in one second. It converts to meters per second by multiplying feet by 0.3048. This unit is common in physics, ballistics, and engineering to express rapid velocities [iso-80000]. Feet-per-second became standardized with the development of modern physics and engineering in the late 19th and early 20th centuries. It was adopted for precise, short-interval velocity measurements in the imperial system [nist-si-guide]. Feet-per-second is widely used in the United States for projectile speeds, fluid flow velocities, and mechanical motion. It is less frequent outside imperial system countries, where meters per second is preferred [nist-si-guide].
What is Second Cosmic Velocity?
Second Cosmic Velocity (v2) is a unit of speed. The second cosmic velocity, also known as escape velocity, is the minimum speed needed to break free from a planet’s gravitational field without further propulsion. For Earth, this speed is about 11.2 km/s, calculated by √(2GM/R) where G is the gravitational constant, M is Earth’s mass, and R its radius [nist-cuu]. Escape velocity was first derived from Newtonian gravity principles in the 17th century and later refined by physicists studying celestial mechanics. It is fundamental for understanding spacecraft trajectory planning [nist-cuu]. Escape velocity is essential in aerospace and astronautics worldwide, guiding mission planning for launches from Earth and other celestial bodies. It is standard knowledge in physics and engineering curricula globally [nist-cuu].
Common Misspellings
People often search for this conversion using these alternate spellings: feet per second, ft per second, feet/sec, fps, second cosmic velocity, cosmic velocity 2nd, escape velocity, cosmic velocity two, cosmic velocity 2. All of these refer to the Feet per Second to Second Cosmic Velocity conversion.
