You can apply Newtons second law anywhere you can push or pull something, its that simple. A little kid throws the ball over the street and he wants it before the car comes, you kick the ball harder so that i goes across the street when he wants it. SIMPLE

Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
its not importsnt
Almost all machinery uses the 2nd Law. Also sports activity and firearms use the 2nd law. The 2nd Law runs the Universe, from the motions of tools to the motions of the galaxies.
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
The clue is in the question.
the second law
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
Every single object that exists obeys ALL of Newtons Laws
F = m a
yea
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).
