Newton's laws of motion, formulated by Sir Isaac Newton, are three fundamental principles that describe the relationship between the motion of an object and the forces acting on it: 1. **First Law (Law of Inertia)**: 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 law highlights the concept of inertia - the tendency of objects to resist changes in their state of motion. 2. **Second Law (Force and Acceleration)**: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Simply put, F = ma (Force = mass × acceleration). This law explains how the velocity of an object changes when it is subjected to an external force. 3. **Third Law (Action and Reaction)**: For every action, there is an equal and opposite reaction. This means that for every force exerted by an object on another object, there is an equal force exerted in the opposite direction by the second object on the first. These laws are foundational in physics, providing a framework for understanding the movement of objects and the forces that cause this movement. ![[Pasted image 20240121134709.png]] [[060 People MOC]]
