Newton's laws of motion are three fundamental principles in physics formulated by Sir Isaac Newton. They describe the relationship between the motion of an object and the forces acting upon it. The three laws are:
1. Newton's First Law of Motion (Law of Inertia): An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
2. Newton's Second Law of Motion: The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. Mathematically, this can be expressed as F = ma, where F represents the net force, m represents the mass of the object, and a represents the acceleration.
3. Newton's Third Law of Motion: For every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.
These laws provide a foundation for understanding the motion of objects and are applicable to a wide range of physical phenomena.
