    That all depends on the planet toward which the mass is falling.

    If this happens to be taking place near the Earth, then the object accelerates

    at the rate of about 9.8 meters per second every second.

    Furthermore, if there is truly no air resistance, then it makes no difference whether

    the object is a feather, a mass of 30 kg, or a school-bus. All objects accelerate at

    the same rate regardless of their mass.
