Newtons law of motion
Sir Isaac Newton formulated three laws of motion, which are fundamental principles in classical mechanics.- First Law (Law of Inertia):
An object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by a net external force.
In simpler terms, objects resist changes in their state of motion.
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. The direction of the acceleration is in the direction of the net force.
Mathematically,
F=m×a, where
F is the force,
m is the mass, and
a is the acceleration.
This law explains how the velocity of an object changes when subjected to an external force.
Third Law (Action and Reaction):
For every action, there is an equal and opposite reaction. If object A exerts a force on object B, then object B simultaneously exerts a force of equal magnitude in the opposite direction on object A.
This law highlights the reciprocal nature of forces between interacting objects.
These laws provide a framework for understanding the relationship between the motion of an object and the forces acting upon it. They are foundational principles in classical mechanics and are still widely used in physics and engineering.
