Part 4 Gage's Blueprint for Truth Rebuttal (Not Debunked): Symmetrical, free fall collapse

Part 4 of Chris Mohr's rebuttal to Richard Gage's controlled demolition theory investigates claims of near free-fall and symmetrical  collapses. 

Note: I am not a scientist, so I cannot be 100% sure of the technical information I share here. For an excellent and respectful rebuttal of my claims from 9/11 Truth activist Adam Taylor, visit https://citizenfor911truth.files.wordpress.com/2014/09/responsetochrismohr4-1.pdf

Clarification: At about 4 minutes in, I use a scale to demonstrate how much more force is generated by falling weight than static load. For a more precise experiment of this kind, which shows 31 times as much force from a single collapsing floor, visit http://www.youtube.com/watch?v=SozKaHYD85Q&feature=player_embedded

A more detailed and complex formula to calculate dynamic force is
Energy = mgh = 1/2 Kx squared dynamic (mass, gravity, height, K = stiffness spring constant, x = deflection distance)

Here's another video showing how and why the buildings collapsed fast but less than freefall: http://www.youtube.com/watch?v=L2cvW2YfvfM&feature=player_embedded

Here is an analysis of the inaccuracies in David Chandler's explanations of the physics of the WTC collapses:

If the three WTC collapses were symmetrical, why did all this happen?
WTC 3 : The structure was destroyed on September 11, 2001 in the collapse of the North and South Towers of the World Trade Center.
WTC 4 : It was damaged beyond repair as a result of the September 11, 2001 attacks and was later demolished ...
WTC 5 : It suffered severe damage and partial collapse on its upper floors as a result of the September 11 attacks in 2001. The entire building was demolished by January 2002 
WTC 6 : Debris from the North tower fell on and around 6 WTC, digging a deep crater into the building's basement, setting it alight. The building's ruins were demolished to make way for reconstruction.
