on a push bike, you provide the force, and this produces acceleration (velocity change), in the form acceleration = force/mass
a speedometer measures instant velocity
Newton's second law is represented by the equation F = ma, which indicates that force is directly proportional to mass and acceleration.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first 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
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).
Newton's second law is represented by the equation F = ma, which indicates that force is directly proportional to mass and acceleration.

its not importsnt
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
the second law
The clue is in the question.
For every action there is an equal and opposite reaction.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.

It isn't closely related. Newton's Third Law is more closely related to conservation of MOMENTUM.
F = m a
