Okay Liza, help me with this. The common argument is that the weight of the top of the buildings was too much and floor after floor was pancaked. Where does the following law of physics apply?
The Law of Momentum Conservation
The above equation is one statement of the law of momentum conservation. In a collision, the momentum change of object 1 is equal to and opposite of the momentum change of object 2. That is, the momentum lost by object 1 is equal to the momentum gained by object 2. In most collisions between two objects, one object slows down and loses momentum while the other object speeds up and gains momentum.
it is my observation that the towers can not fall at near free fall speed with a skyscraper beneath it.
Momentum Conservation Principle
So please, using this one very simple law of physics explain it to me. Without directing me elsewhere.
