    The derivation of this is very simple: just combine newton's acceleration equation with his graviity equation and solve for "a".

    It is because the each unit mass is affected by same gravitational force.

    But in normal life for example
    when we hit the ball by our hand,only some part of the ball gets this external energy directly and this energy is distributed to whole spherical ball .This makes the less heavy material to accelerate more and heavier material to accelerate less.
    But the gravity is interaction with each unit mass,where each unit suffers 9.8m/s^2
