Question

Need some secondary evidence for an experiment seeing how the mass of an object effects the rate of fall.

Answer 1

Any object will fall at the same acceleration within a vacuum. In air a heavy object (lead ball) will push through wind resistance easier than a light object (hair ball). Each proton or neutron is attracted to the earth's center of gravity equally and individually or within a large mass. A bag full of marbles will fall at the same rate whether they are glued together or not.

Answer 2

Yes it Does if the mass increases the speed of the object gets doubled but if the velocity of the object increases then the speed at which the the object is falling is quadrupled
