Newton's first and third laws of motion don't contribute anything to an understanding
of Kepler's laws of planetary motion.
Kepler's laws can be derived from Newton's law of universal gravitation, along with his
second law of motion.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
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).
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.

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

Law of Inertia.
It isn't.
It is associated with the law of gravitational pull.
