In a vacuum where there is no air resistance, both a hammer and a feather will fall with the same acceleration due to gravity. Therefore, the values that will be the same for both objects are the gravitational attraction between them and the Earth, the velocity of the objects (when considering their velocities at the same instant during the fall), and the time it takes for them to fall from the same height to the ground.
The only value that would be different under normal conditions (without air resistance) between a hammer and a feather is:
**the upward push of air resistance.**
In a vacuum, however, since there is no air resistance at all, this aspect becomes irrelevant. Therefore, the answer in a vacuum situation is that none of the values will be different. However, generally speaking (outside a vacuum), the upward push of air resistance would be the one that differs under normal conditions.
In this context, if we strictly refer to a vacuum scenario, the correct interpretation would be that **all values will be the same**.
