When objects are accelerating due to gravity, the mass of the object doesn't matter. Galileo demonstrated this by dropping a cannon ball and a bullet from a height, and they hit the ground at the same time. So no, gravity doesn't 'push' or 'pull' either upwards or downwards - is an attractive force between two masses.
Boru
Actually, if one considers the gravitational pull of the cannon ball and the bullet, the cannon ball must fall faster, albeit a negligible difference in that experiment.
Although not if you drop them next to each other, at the same time from the same height
