Newton's laws of motion is one of the clasical branches in physics. These three laws show the relations between the forces acting on a body and the motion of the body. Together, these laws provide a framework for understanding and predicting the motion of objects and the forces that govern their behavior. They form the basis of classical mechanics and have extensive applications in physics, engineering, and everyday life.
Newton's first law of motion, also called law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant velocity, unless acted upon by an external force. In simpler terms, the first law states that objects tend to "keep doing what they're doing" unless something makes them do otherwise. If an object is stationary, it will stay stationary unless a force is applied to it. If an object is already in motion, it will keep moving in the same direction and at the same speed unless a force acts on it to change its motion.
Newton's second law of motion, also called law of resultant force, describes the relationship between the motion of an object, the net force acting on it, and its mass. It states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In simpler terms, the second law states that the acceleration of an object is directly related to the force applied to it. If a greater force is applied to an object, it will experience a greater acceleration. Similarly, if the mass of the object is increased, it will experience a smaller acceleration for the same force.
Newton's third law of motion, also called law of actions and reaction, states that for every action, there is an equal and opposite reaction. It means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object. In simpler terms, if object A applies a force on object B, then object B simultaneously applies an equal and opposite force on object A. These two forces always occur as a pair, acting on two different objects.
