summaryLong: |-
  Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows:A body remains at rest, or in motion at a constant speed in a straight line, unless it is acted upon by a force.
  At any instant of time, the net force on a body is equal to the body's acceleration multiplied by its mass or, equivalently, the rate at which the body's momentum is changing with time.
  If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.
lede: Isaac Newton published Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) in London on July 5, 1687, laying out three laws of motion that became the foundation of classical mechanics. The work explained how objects move and interact through force, replacing centuries of intuition-based physics with mathematical precision. It remained the dominant framework for understanding the physical world for more than two centuries.

impactStatement: Newton's three laws—inertia, force-acceleration, and action-reaction—unified terrestrial and celestial mechanics under a single mathematical framework. The Principia didn't just explain existing observations; it made physics predictive and quantifiable, enabling everything from ballistics to orbital mechanics. Few individual publications have so thoroughly reshaped humanity's relationship with how the world actually works.
