Very well authored indeed.

However, as a student my Physics teacher had introduced Newton's Second Law of Motion as below:

All bodies of any mass tend to remain in their own state of rest or uniform rectilinear motion unless an externally imoressed force acts on them to cause a change in their state of motion;

And for a body of mass 'm', to achieve an acceleration 'a', it requires an externally impressed force 'F' in the direction of acceleration such that F=m*a.

I still don't see anything wrong with it.
