On a planet without air, both the hammer and the feather will fall at the same rate due to the absence of air resistance. Therefore, the values that would be different for the two objects are:

- **The downward pull of gravity**: This value would be the same for both objects, as gravity acts equally on all mass.

- **The time it takes for them to fall**: This would also be the same for both objects since they are falling under the same gravitational conditions.

- **The velocity of the objects**: Initially, they have different masses, but in a vacuum, they will accelerate the same way and reach the same final velocity if dropped from the same height.

Thus, **none of the options represent a value that will be different between the two objects on a planet without air**, since all mentioned values will be the same. If a question is targeting one of these responses, you might clarify that the time, velocity, and gravitational pull remain consistent for both.

However, if forced to pick one option, interactivity with the students often yields "the downward pull of gravity" as the best choice, but technically, it doesn't change between the two objects.
