Dear Ishan
 

If an object has no acceleration in one inertial frame of reference that means no real forces acting on it. now suppose you observe the same object from a different inertial frame,its not possible that just because you are observing the same object from a different inertial frame somehow a real force will start acting on the object. But if you observe now the same object from an noninertial frame of reference then fictitious forces will act on the object and here the object can have acceleration without some real forces acting on it.

That means you first calculate the net force acting on a particle in one inertial frame of reference and then calculate net force from a different frame of reference(Inertial or noninertial) . If the net force is not same(for both frames) means some fictitious forces are acting on the particle. If there are fictitious forces then you are observing now from a non inertial frame of reference.
