His first law, often called the law of inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. This idea revolutionized the way people thought about motion, shifting the focus from forces to the behavior of objects themselves.
Newton’s second law of motion explains how the velocity of an object changes when it is subjected to an external force. It establishes a direct relationship between force, mass, and acceleration, formulated as F = ma (force equals mass times acceleration). This law provided a mathematical framework for predicting how objects would move under various forces, making it a cornerstone of classical mechanics. The precision and clarity of Newton’s second law allowed scientists and engineers to design everything from simple machines to complex structures with a deep understanding of the forces at play.
The third law of motion, which states that for every action, there is an equal and opposite reaction, further solidified Newton’s influence on physics. This principle explains a wide range of phenomena, from the recoil of a gun to the propulsion of rockets. By demonstrating that forces always come in pairs, Newton provided a comprehensive explanation for interactions between objects.
