Newtonian physics is a branch of classical mechanics that describes the motion of objects based on the laws formulated by Sir Isaac Newton in the 17th century. It focuses on concepts such as force, mass, and acceleration, explaining how objects move and interact in our everyday world. The three fundamental laws of motion provide a framework for understanding how forces affect the movement of objects. These laws state that an object at rest stays at rest unless acted upon by a force, that the acceleration of an object is directly proportional to the net force acting on it, and that for every action, there is an equal and opposite reaction. Newtonian physics is essential for understanding basic physical phenomena and is widely applied in engineering and technology.
