Question

Which objects exert gravitational force? (All objects exert a gravitational force on all other objects; Only objects that are close to each other exert a gravitational force;

Answer 1

All objects exert a gravitational force on all other objects. This is a fundamental principle of gravity as described by Newton's law of universal gravitation. According to this law, every mass attracts every other mass in the universe, with the force of attraction being proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Therefore, even extremely small objects exert gravitational forces, though they may be negligible compared to more massive bodies.
