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. These laws form the basis of classical mechanics and are essential in understanding how objects move.
1. First Law (Law of Inertia):
An object at rest stays at rest, and an object in motion stays in motion at a constant velocity, unless acted upon by an external force.
This means that objects resist changes in their state of motion unless a force is applied.
2. Second Law (Law of Acceleration):
The force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).
This describes 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 when one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first.
These laws provide the foundation for much of classical physics and are used in everything from understanding the motion of planets to designing vehicles.
