Final answer:
The term for the dominance of one force over another, ensuring operational freedom without opposing interference, is 'sphere of influence.'
Step-by-step explanation:
The term used to describe the degree of dominance in space of one force over another that permits the conduct of operations without prohibitive interference by the opposing force is known as sphere of influence. In a global context, this can relate to a state's sovereignty, or its ability to operate without external interference. Factors that contribute to a state's dominance could include its military might, economic strength, or technological advancements. In an international relations context, this dynamic can be observed in unipolar, bipolar, and multipolar systems where states exert power and strive for a balance of power, sometimes leading to collective security arrangements or resulting in anarchy where there is no overarching authority.
