Ummn objects don't fall according to thier wieght. A heavier object will not hit the ground before a lighter object.
All objects (near the earth's surface) experience a constant downward acceleration of g = 9.81 (m/sec)/sec, regardless of what their mass was.
Imagine you had two cannon balls of exactly the same shape and dimensions, one was hollow and the other soild.. if you dropped these from a great hieght at exactly the same time they would hit the floor at exactly the same time.
To summarize, we know the acceleration an object experiences (due to the gravitational attraction between the earth and the object) does depend on its height above the surface of the earth. However, if the object is reasonably close to the earth's surface, the acceleration it experiences does not change by much (even if the height of the object is 1000 meters above the earth's surface). As a result, in most cases, we may assume the object experiences a constant downward acceleration of g = 9.81 (m/sec)/sec.
