4. Newton’s Laws of Motion
Isaac Newton’s three laws of motion, articulated in his landmark work “Philosophiæ Naturalis Principia Mathematica” (Mathematical Principles of Natural Philosophy), are among his most enduring contributions to science. Published in 1687, Newton’s laws laid the foundation for classical mechanics and provided a comprehensive framework for understanding the motion of objects under the influence of forces.
-
First Law (Law of Inertia): An object at rest will remain at rest, and an object in motion will remain in motion unless acted upon by an external force.
-
Second Law (Law of Acceleration): The rate of change of momentum of an object is directly proportional to the force applied, and the change in momentum occurs in the direction of the applied force.
-
Third Law (Action-Reaction Law): For every action, there is an equal and opposite reaction.
These laws not only explained phenomena observed on Earth but also provided the theoretical framework for understanding celestial mechanics and the motion of planets.
