If force is something that changes the state of a body and inertia is opposition to change of state how can gravitational force be proportional to mass?

Gravity is a fundamental force of nature that causes objects with mass to attract each other. It is responsible for keeping planets in orbit around the sun and for the formation of stars and galaxies.
The strength of gravity is directly proportional to the mass of an object. This means that the more massive an object is, the stronger its gravitational pull will be.
Inertia is a property of matter that describes an object's resistance to change in motion. It is directly proportional to an object's mass, meaning that the more massive an object is, the more inertia it has.
According to Newton's first law of motion, an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force. This is due to the combination of gravity and inertia - gravity pulls objects towards each other, while inertia keeps them in motion.
In space, where there is no air resistance, objects will continue moving in a straight line at a constant speed unless acted upon by a force. This is because the effects of gravity and inertia dominate in the absence of other forces. This is why objects in orbit around a planet or star will continue to orbit in a stable path.
