When a ball is kicked at an angle, there is no acceleration along the horizontal direction (since there isn't any force along the direction ,ignoring viscous forces), so , its velocity along the horizontal direction remains unchanged....
according to the 1st law , velocity changes only when a net resultant force is applied on the ball , so , Newton's law is valid. only the initial angle of kick and the vertical component of velocity are mainly responsible for the distance travelled by the ball horizontally....
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 Third Law applies everywhere.
because it just does
no
the law of inertia
yeah.
Law of inertia.
h
Newtons first law
Law of Inertia.
It isn't.
It is associated with the law of gravitational pull.
