What are Newton’s Laws of Motion?

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. The first law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force. This principle emphasizes inertia, which is the tendency of objects to resist changes in their state of motion.

The second law quantifies the effect of force on an object’s motion. It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed with the formula F=ma, where F is force, m is mass, and a is acceleration.

The third law asserts that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs; when one object exerts a force on another, the second object exerts a force of equal magnitude but in the opposite direction on the first object.

These laws were formulated by Sir Isaac Newton in the late 17th century and are foundational to classical mechanics. They provide a framework for understanding how objects behave in motion and are applicable in various real-world scenarios, from everyday activities to complex engineering systems.
