C Correct answer
Explanation

In a vacuum, all objects fall with the exact same acceleration due to gravity, regardless of their mass or composition, as established by Galileo. Speed and velocity change continuously during free fall, so they are not constant. Force depends on mass, so different objects experience different gravitational forces.
