Newton's first law of motion 'Everybody retains its state of rest or state of motion, until an external force Is applied on it. A Person sitting in a moving car fall forward , when the car stops suddenly. Athlete run some distance , before taking a long jump.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Newton's first and third laws of motion don't contribute anything to an understandingof Kepler's laws of planetary motion.Kepler's laws can be derived from Newton's law of universal gravitation, along with hissecond law of motion.
it doesnt
It isn't.
Newtons Second Law was F=ma, means the force(F) acting on object is equal to mass(m) of object times it's acceleration(a).

the law of inertia

yeah.
Law of inertia.
it doesnt
the external effort causes the object to move then stops with a obstacle in the way
h

It is associated with the law of gravitational pull.
