Final answer:
The gravitational force is always attractive and depends on the masses of the objects and the distance between them.
Step-by-step explanation:
The gravitational force is always attractive and depends on the masses of the objects and the distance between them. Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
