Newton's 2nd Law can study the motion of the objects in the case of zero net force:

**F**= m

**a**

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.
