The object accelerating downward exerts less force on the part below than if it were being held in place, But this is a reflexive situation: the lower section exerts less retarding force on the descending object - Newton's 3rd law. If the retarding force were greater, the object would have less downward acceleration and, if the force were great enough for long enough time, there could be arrest.

I wanted to know if I had this right? I think it is correct from what I have tried to research.

Any input would be appreciated, thanks

BUMP please...anyone?
 
There isn't enough information to answer your question. What the force would be depends upon how fast the dropped object takes to stop.
