Answer :
Final answer:
To store gravitational potential energy, increasing the distance between masses in the Earth-Moon system is required.
Explanation:
Gravity is the force of attraction between masses, dependent on mass and distance. In the Earth-Moon system, to store gravitational potential energy, increasing the distance between them would be needed. This separation between two objects with mass enhances their potential energy due to the inverse relationship between potential energy and distance under gravity's influence.
