About Newton
Definition: The newton (symbol: N) is the SI unit of force, defined as the force needed to accelerate one kilogram of mass at one meter per second squared.
History: Named after Sir Isaac Newton in 1946. Adopted as standard SI unit to replace various national force units.
Current Use: Universal standard for force measurement in engineering, physics, and scientific applications worldwide.
Examples: Apple weight: 1 N, handshake: 20-30 N, car engine: 5,000-15,000 N, rocket thrust: millions of N
About Pound-force
Definition: The pound-force (symbol: lbf) is the force needed to accelerate one pound of mass at 32.174 feet per second squared.
History: Imperial force unit developed from the pound mass and standard gravity. Standardized for engineering use.
Current Use: Primary force unit in United States engineering, aerospace, and mechanical applications.
Examples: Person weight: 100-250 lbf, car engine: 300-800 lbf, aircraft thrust: 10,000-100,000 lbf
