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
the law of inertia
yeah.
Law of inertia.
h
Law of Inertia.
It isn't.
It is associated with the law of gravitational pull.
probably a bowling ball and a soccer ball. please be careful with the bowling ball though.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
