Poundal (FPS Absolute Force Unit)

Introduction : A poundal is the force required to accelerate a one-pound mass at one foot per second squared. It is equal to approximately 0.138255 newtons and comes from the absolute FPS (foot-pound-second) system of units.

History & Origin : Created as part of the British Absolute FPS system, the poundal addressed the need for consistent force definitions based on Newton’s second law. It was used primarily in physics education and classical mechanics literature in the early 20th century.

Current Use : Now largely obsolete, poundals are occasionally used in physics textbooks and legacy academic documents. They offer insight into early mechanics frameworks and are referenced in educational settings focused on classical dynamics.

Teranewton (Theoretical Extreme Force Unit)

Introduction : The teranewton is equal to one trillion newtons. It is a theoretical unit often used in astrophysics and high-energy simulations where enormous magnitudes of force are discussed.

History & Origin : Introduced as part of the SI system’s expanded prefixes, teranewtons remain largely academic, useful for calculations in quantum mechanics, celestial collisions, or planetary impacts.

Current Use : Primarily appears in research and scientific papers on high-energy phenomena like black hole collisions, nuclear interactions, and planetary dynamics. Not used in practical engineering.
