Newton's First and Second laws, in Latin, from the original 1687 Principia Mathematica. Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
Inertia & Newtonâs First Law of Motion. A body, such as a soccer ball, will remain at rest unless acted upon by an external force. Isaac Newtonâs First Law of Motion describes the behavior of a massive body at rest or in uniform linear motion, i.e., not accelerating or rotating.
