The famous physicist who formulated the laws of motion is Sir Isaac Newton. He proposed three fundamental laws that describe the relationship between a body and the forces acting on it, laying the groundwork for classical mechanics. Newton's first law states that an object at rest remains at rest unless acted upon by a force. The second law introduces the concept of force being equal to mass times acceleration (F=ma), while the third law asserts that for every action, there is an equal and opposite reaction. His work, encapsulated in "Philosophiæ Naturalis Principia Mathematica," significantly advanced the field of physics.
