A lot of people can't get their head around physics, ask anyone 'When a bug hits a windshield, which one experiences the most force', and most will get it wrong. Most people think something moving fast is going to put more force on something that is stationary, or the bigger objects will put more force on the smaller object, both are incorrect.

Well here is a CHALLENGE for all the truthers on here IF you think that the mass falling on both towers above the aircraft impact points could not cause a total collapse can you please SHOW how you calculated the impact force that was generated.
So for the North Tower what would the impact force be on the floor level when the 15 floors above fell?
The South Tower 31 floors, now to make things easy just use the 700 tons of concrete that each floorslab had!
Lets see how you guys work that out!!!!
So for the North Tower 15x700 tons = 10500 The South 31x700= 21700 tons. Drop distance 12 feet (one floor)
So lets see how you guys work out what force would be generated???
How do you calculate the amount of energy necessary to crush each level of the building when we aren't even told the amount of steel on each level of the building? So build a model that can completely collapse.

The floor slab would have been 600 tons. I have never seen the weight of the pans and trusses specified. But what was the weight of steel in the core on each level. That was not constant down the building.

show me how my equation is wrong. use math...go on, i dare you. you can say "eww, truther math is crap" all day, but you never care to show how it is wrong.
so (15x*9.8)-(90x*9.8) = -735
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
That part is wrong.
It should be:
(15 x 9.8) - (1 x 9.8)
The only guy to ever supply ant calcs to the collapse, Gordon Ross, agrees that the whole lower part of the building supplies resistance at the same time/moment of first impact.
Fail
And every 12' ke is regained in the space between floors, where it is reaccelerated by gravity.
To simplify this question for you what he is asking is: in the formula
F=Ma
how do you calculate "a" ? Can you even describe to us what "a" represents.
We want to know what you think "a" is and put it in a F=Ma equation for us.
So in your mind, it should be impossible for a man to break 12 concrete slabs or wooden boards with one swing of his hand, right? I mean equal and oposite reaction, the hand should be stopped, right?

The FLOORS ARE SUSPENDED , NO floorslab below supports a floorslab above they can fall between the walls and core!!!!
The coulums below support the mass of the column above is that REALLY to difficult for you to understand!!
In practice, buckling is characterized by a sudden failure of a structural member subjected to high compressive stress, where the actual compressive stress at the point of failure is less than the ultimate compressive stresses that the material is capable of withstanding
The force that would be generated was so high the floorslabs provided little resistance as I said you only had to shear the bolts, the angles or the welds around the angles!
