About Knots per second

The knot per second (kn/s) equals 1852/3600 m/s² ≈ 0.5144 m/s², used in aviation and maritime operations where speed is measured in knots. Aircraft carrier catapult launches accelerate an F/A-18 from 0 to ~150 kn in 2-2.5 s, giving 60-75 kn/s ≈ 31-39 m/s². A commercial jet rejected takeoff from V1 (~145 kn) to rest in ≈25 s decelerates at 5-6 kn/s ≈ 2.6-3.1 m/s². 1 kn/s = 463/900 m/s² ≈ 5.25 × 10⁻² g₀.

About Gal

The gal (Gal) equals 1 cm/s² = 0.01 m/s², named after Galileo Galilei in recognition of his free-fall experiments. Earth's surface gravity is approximately 980 Gal; the GRS80 normal gravity formula gives 978.03 Gal at the equator and 983.22 Gal at the poles. The BIPM SI Brochure recognises the Gal as a non-SI unit accepted in geophysics. 1 Gal = 0.01 m/s² = 1 cm/s² = 1000 mGal ≈ 1.02 × 10⁻³ g₀.
