Hi,
Newton's 2nd Law can study the motion of the objects in the case of zero net force:
F = ma
if F = 0 then a = 0 then v = constant, then the object is either at rest (v=0) or moving in uniform rectilinear motion. (Bold quantities are vectors).
What is the point of Newton's first law as it is nothing more than a special case of Newton's 2nd Law?
I am sure there is a good reason that Newton himself stated his first law as a separate law, but I can not see this reason.
