Final answer:
A larger/heavier mass has a stronger gravitational attraction, and if the objects are further apart, the attraction is weaker, aligning with Newton's law of gravitation.
Step-by-step explanation:
When we discuss the nature of the force of gravity, we're talking about the attraction that occurs between any two bodies that have mass. According to Newton's universal law of gravitation, larger/heavier masses exert a stronger gravitational attraction, while the force diminishes with an increase in distance between the objects. Therefore, the correct answer to the question is that a larger/heavier mass has a stronger attraction, and if the objects have a long distance between them, the attraction is weaker.
So, the complete answer is: A larger/heavier mass has a stronger attraction while if the objects have a long distance between them, the attraction is weaker.
