Newton's Laws of Motion are three fundamental principles that describe the relationship between the motion of an object and the forces acting on it. Here they are stated:
Newton's First Law (Law of Inertia): An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by a net external force. In simpler terms, objects tend to maintain their state of motion (either at rest or moving with constant velocity) unless a force changes that state.
Newton's Second Law (Law of Acceleration): The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this is expressed as , where is the net force applied to the object, is its mass, and is its acceleration. This law explains how the motion of an object changes when a force is applied to it.
Newton's Third Law (Action-Reaction Law): For every action, there is an equal and opposite reaction. When one object exerts a force on a second object, the second object simultaneously exerts a force of equal magnitude but in the opposite direction on the first object. This law illustrates the mutual interaction between two objects and the conservation of momentum.
Together, these laws form the basis of classical mechanics and are essential for understanding and predicting the motion of objects in the universe. They provide a framework for analyzing the behavior of objects under the influence of forces and have applications ranging from everyday situations to advanced physics and engineering.
