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. They were formulated by Sir Isaac Newton in the 17th century and are as follows:
1. Newton's First Law (Law of Inertia): An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
2. 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. This can be mathematically expressed as F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
3. Newton's Third Law (Law of Action and Reaction): For every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
These laws are fundamental to our understanding of how objects move and interact with each other in the physical world.

Newton's Laws of Motion
First Law (Law of Inertia):
- Objects at rest remain at rest, and objects in motion remain in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
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: F = ma (Force = mass x acceleration)
Third Law (Law of Action-Reaction):
- For every action, there is an equal and opposite reaction. - When one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object.
