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.
Newton's First Law of Motion states that an object at rest will stay at rest unless an unbalanced force is applied to it, and that an object moving at a constant velocity will continue to move at that velocity unless an unbalanced force is applied to it. Imagine two friends pushing against a box in opposite directions.
