first law : an object is at rest unless an force is applied to the object
second law : acceleration of the body is directly proportional to mass and
invertionally proportional to the object
third law: to every object there is equal and opposite reaction which acts on two different bidies

1st law
"A body remains at rest or in uniform motion until and unless an external force acts upon it.
The basis of this law means that if an object is not moving it will only move when a force is applied onto it, as well as an object that is in motion will not change its velocity (accelerate) until a net force acts upon.
Newton's Second Law
"The rate of change of momentum of an object is proportional to the resultant force acting on the body and is in the same direction."
This law means that the force of the object moving will be equal to the opposing force such as air resistance.
Newton's Third Law of motion
"All forces occur in pairs, and these two forces are equal in attitude and opposite in direction." It can be said that "every action has opposite and equivalent reaction"
Examples
When we push a wall, it creates an opposite amount of force, thus, either we move or does the wall move.
