Two objects of different masses falling freely near the surface of the Moon would
Answer: C
They would have same velocity at any instant.
Near the Moon's surface, as near the Earth's, every freely falling object has the same acceleration due to gravity, whatever its mass (about 1.6 m/s2 on the Moon), and the Moon has no air to slow lighter objects. Released together from rest, both objects therefore have the same velocity at every instant.
They do not have different accelerations. Inertia depends on mass, which does not change as they fall. The gravitational forces on them are proportional to their masses, so they are not of the same magnitude.
