Final answer:
The subject of this question is Physics. The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Large masses that are close together will result in the most significant gravitational force.
Step-by-step explanation:
The subject of this question is Physics. Physics is the branch of science that deals with the study of matter and energy and their interactions. In this case, we are specifically discussing the gravitational force and how it depends on the masses involved and the distance between them.
The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This means that the force becomes stronger as the masses increase and weaker as the distance between them increases. Therefore, large masses that are close together will result in the most significant gravitational force.
