Force (Mechanics)
Force is a fundamental physical vector quantity that describes an interaction capable of changing the motion of an object. In classical mechanics, force is defined by Newton's second law of motion as the product of mass and acceleration. Measured in SI units as the newton (N), force encompasses gravitational, electromagnetic, and mechanical interactions, ranging from macroscopic structural loads to subatomic particle dynamics.
