Newtons Law

Sir Isaac Newton's three laws of motion are foundational to classical mechanics. The First Law states that an object remains at rest or in uniform motion unless acted upon by a force, the Second Law quantifies the relationship between force, mass, and acceleration, and the Third Law emphasizes that every action has an equal and opposite reaction. Together, these laws describe how objects respond to forces and are essential for understanding physical motion.

Newton's Laws of Motion Detailed Notes

Sir Isaac Newton formulated three laws of motion in the 17th century
that form the foundation of classical mechanics.

1. First Law (Law of Inertia):


An object remains at rest or moves in a straight line at a constant
velocity unless acted upon by a net external force. This law explains
why seatbelts are necessary — a moving body will keep moving
unless something stops it.

2. Second Law (F = ma):


The force acting on an object is equal to the mass of that object
multiplied by its acceleration. This means that heavier objects
require more force to accelerate, and this law quantifies the effect of
force on motion.

3. Third Law (Action-Reaction):


For every action, there is an equal and opposite reaction. If you push
on a wall, the wall pushes back with the same force in the opposite
direction. This principle is also why rockets are able to propel
themselves in space.

These laws explain how objects respond to forces and are fundamental to
understanding physical motion in our universe.
