Collapse of WTC towers

    Collapse of WTC towers....

    Hi all,

    I am a Layman in physics unfortunately, this is my first post so be kind please.

    I Know that an object accelerating downward exerts less force on the part below than if it were being held in place, But how does this relate to the top section of the WTC falling on the below section? Some people say because of that statement, the second lower section should arrest the falling upper section. I do not think that should happen though, as it did not in reality.

    Your thoughts would be appreciated.

    Thanks
