What is a property of gravitational fields?

Gravitational fields are characterized by the way they exert a force on objects that possess mass. The correct answer highlights that the force felt by an object in a gravitational field depends on both the mass of that object and the distance from the source of the gravitational field. According to Newton's law of universal gravitation, the gravitational force between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This principle demonstrates that as an object's distance from the mass creating the field increases, the gravitational force it experiences diminishes; conversely, a greater mass will exert a stronger gravitational pull.

The other options do not accurately reflect essential characteristics or principles of gravitational fields. For instance, gravitational fields are not limited to existence only in space; rather, they can extend through space and influence objects situated within them. Additionally, gravitational fields are not uniform; their strength varies depending on the distance from the mass generating the field. Finally, while gravitational fields are stronger near large masses, they do exist in the vicinity of smaller masses as well, though with a significantly weaker force. Thus, understanding the nature of gravitational fields requires recognizing the dependence of the force on both mass and distance, which is succinctly captured
