Force is measured in Newtons, named after Sir Isaac Newton, who made significant contributions to physics, particularly in his formulation of the laws of motion. A Newton (N) is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared. In practical applications, Newtons are critical in various fields including engineering, mechanics, and physical sciences, as they quantify how much force interacts with objects. Understanding this measurement helps scientists and engineers calculate the effects of force in various situations, from simple tasks to complex designs.
