Mass does not affect gravity?

    From the eqn of motion deduced, I can say that two body, one of 50 kg, and one of 50 g if allowed to freely fall from same height, they will reach the ground the exact same time?? Practically is it possible? How ? They are largely different but same distance in same time????

    Yup. Well, in a vacuum anyway.

    You've seen the demos of different masses falling in a vacuum, right?

    Pretty sure the Apollo astronauts did this demo on the moon for fun -- Googling now...

    Small caveat: when you drop a rock toward Earth, you are also dropping the earth toward the rock. What does flipping the situation over tell you?
