Expert Answer:

Newton's second law states that rate of change of momentum of object equals the force acting on it.
If force acting on it is zero , then change in momentum is zero and there is no state of change of motion of object.
Hence according to first law , in absence of external force , the object continues its state of motion .
If any change in state of motion , then this change in state of motion is due to external force
