Newton's first law states that an object at rest stays at rest and an object in motion continues in motion with the same speed and in the same direction unless acted upon by a net external force. This means that if there is no net force acting on an object, its velocity will remain constant.
On the other hand, Newton's second law states that the acceleration of an object is directly proportional to the net force acting upon it and inversely proportional to its mass, expressed as $F = ma$.
If we consider a situation where the net force acting on an object is zero (i.e., $F = 0$), then according to Newton's second law, the acceleration $a$ will also be zero. This results in the object maintaining its state of rest or uniform motion, which aligns with the statement of Newton's first law.
Therefore, when the net force is zero, the implications of Newton's second law lead us to the conclusion described in Newton's first law, making it a special case of the second law.
Thus, Newton's first law is indeed a special case of the second law.
