It's a strange and fascinating fact that in asking your question, you've used EXACTLY the same
wording as another person, who posted EXACTLY the same question here on WikiAnswers, did ...
and both of your questions apparently refer to the same drawing or picture or previous description
that neither of you has included with your question. It's almost as if the two of you are either
identical twins separated at birth, or else both trying to get WikiAnswers volunteers to do your
homework or take your test for you. Fascinating!
Anyhow, since you mention "the falling body", we think you're actually asking whether heavier
objects fall with the same or different accelerations compared to lighter ones.
The answer is that as long as you test all of them on the same planet, and they don't run into
too much air, the lightest feather and the heaviest battleship, and everything in between, all
fall with the same exact acceleration.
Your question describes it as a "falling body", so I'm assuming that you're asking about a body with no force on it except for the gravitational force. This is an important assumption. If it's true, then the mass (weight) of the falling body has no effect at all on its acceleration. Except for the effect of air resistance, all bodies fall with the same acceleration.
From f = m*a, a = f/m, so if the force remains constant and the mass increases, the acceleration will decrease. But if the block is on an incline and the force is provided by gravity, the force will increase directly proportional to the mass of the block, and acceleration will remain the same.
False
they arent falling at the same speed because gravity is stronger with a heavier object
Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.

Salt water is heavier, as it has salt disovled in it. This can be observed in some underwater caves.
because it's heavier
False
yes it does it makes it heavier which in turn slows acceleration unless more force is added to move the object
they arent falling at the same speed because gravity is stronger with a heavier object
The one that is heavier
Yes. The acceleration depends on the aerodynamics of the shapes of the objects - not their mass.
false
no, they fall the same acceleration ( one gravity ) neglecting air resistance; however they may reach different velocities with air resistance.
