There are three laws of motion formulated by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica published in 1687:
1. Newton's First Law of Motion:
An object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by an external force. This is also known as the law of inertia.
2. Newton's Second Law of Motion:
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be expressed as the formula F = ma, where F is the force applied, m is the mass of the object, and a is the acceleration.
3. Newton's Third Law of Motion:
For every action, there is an equal and opposite reaction. This means that if one object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.
These laws are foundational principles of classical mechanics and have been key in our understanding of motion and forces in the physical world.
