Newton’s Laws of Motion
1. First Law (Law of Inertia): An object at rest tends to stay at rest, and an object in
motion tends to stay in motion unless acted upon by an external force. In other words,
an object’s natural state is to maintain its current motion or lack thereof.
2. Second Law (Law of Acceleration): 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=maF=ma
where:
○ (F) represents the net force acting on the object.
○ (m) is the mass of the object.
○ (a) is the acceleration produced.
3. Third Law (Action-Reaction): For every action, there is an equal and opposite
reaction. When one object exerts a force on another, the second object responds with
an equal force in the opposite direction.
These fundamental laws, formulated by Sir Isaac Newton, provide the foundation for
understanding how objects move and interact in our physical world. Whether you’re
launching a rocket or simply pushing a book across a table, these principles govern the
behavior of matter.
