The scientist known for the laws of motion is Sir Isaac Newton. He formulated three fundamental laws that describe the relationship between the motion of an object and the forces acting upon it. Newton's First Law states that an object will remain at rest or in uniform motion unless acted upon by an external force. The Second Law introduces the concept of force as the product of mass and acceleration (F=ma). The Third Law states that for every action, there is an equal and opposite reaction. Newton's work laid the groundwork for classical mechanics and profoundly impacted the fields of physics and mathematics.
