Gravitational force of attraction between two bodies always depend on their masses. However, the acceleration due to
gravity does not depend on the mass of the body.
During free fall, the heavier objects as well as the lighter objects fall with the same acceleration towards the surface of
the earth, since the acceleration due to gravity does not depend on the mass of the body. The slow speed of feather, while
falling, is due to the fact that its surface area is very large as compared to its mass, so the feather experiences much more
resistance from air and its speed is slowed down. However, the brick, being small and heavy, does not get much air
resistance and falls to the ground at a faster rate
