# Newton's First Law

Newton's First Law, often referred to as the law of inertia, lays the foundation for classical mechanics by elucidating the fundamental principle that an object at rest remains stationary, and an object in motion persists in a straight line at a constant velocity unless acted upon by a net external force. Sir Isaac Newton's groundbreaking formulation of this law in the 17th century revolutionized our understanding of motion, providing a crucial framework for subsequent developments in physics and engineering. This law's simplicity conceals its profound implications, forming the cornerstone of Newtonian physics and shaping our comprehension of the physical world.
