Final answer:
Gravity is inversely proportional to the square of the distance between two objects and depends on the mass of the objects involved.
Step-by-step explanation:
The accurate statement about the force of gravity is that it is inversely proportional to the square of the distance between two objects. As the distance between objects decreases, the force of gravity increases. This relationship is expressed by Newton's law of universal gravitation. On the other hand, gravity is not directly proportional to mass, as the force also depends on the mass of the objects involved. Therefore, option 2 is accurate.
