Newtonian Mechanics is a branch of physics that describes the motion of objects and the forces acting upon them. Developed by Sir Isaac Newton in the 17th century, it is based on three fundamental laws of motion. These laws explain how objects move in response to forces, such as gravity and friction, and help us understand everyday phenomena, from a falling apple to a car accelerating on a road. This framework is essential for analyzing the motion of everything from small particles to large celestial bodies. Although it has limitations at very high speeds or in strong gravitational fields, Newtonian Mechanics remains a cornerstone of classical physics and is widely used in engineering and everyday life.
