The Newton (N) is the standard unit of force in the International System of Units (SI). It is defined as the force required to accelerate a one-kilogram mass at a rate of one meter per second squared. In other words, 1 N = 1 kg·m/s². This definition is derived directly from Newton’s Second Law of Motion, which states that force equals mass times acceleration (F = ma). The Newton is a relatively small unit in practical applications, so larger forces are often expressed in kilonewtons (kN), where 1 kN = 1000 N. The Newton provides a consistent and universal way to measure force in engineering, physics, and mechanical design, ensuring compatibility across different fields and applications.
