The building's collapse DID accelerate at a speed indistinguishable from free fall. That is a fact. It has been measured and verified, even by the liars at NIST despite them trying to first deny it. Free fall in Newtonian physics is the motion of an object where the only force acting upon it is its own weight. Weight is the force on an object due to gravity. NIST calculated that WTC7 was in free fall for 2.25 seconds. That could only have been done if several floors and supporting structures were blown out at specifically timed intervals allowing the structure to fall unimpeded to where it could reach a rate of acceleration. That could not happen in a scenario with gradual weakening of support structures due to fire where the resistance from each floor hitting the one below would cause deceleration in the fall due to resistance. Look at video of acknowledged controlled implosion demolitions and notice how they blow out several floors. As the buildings collapse the rate of the fall accelerates. Here, I'll include some for you:
Landmark Tower implosion:
Aladdin Hotel implosion:
Everglades Hotel implosion:
West Palm Beach condo implosion:
Now, in case you don't take my word for it you can check out David Chandler's video analysis of NIST's treatment of the WTC7 free fall issue from which I obtained the information in my last comment. Mr. Chandler is a high school physics teacher. I assume these should be sufficient credentials for you considering you cited your position as a middle school teacher whose curriculum includes teaching fallacies to demonstrate that you are a sort of authority on that particular subject in your "Truthers continue to see what they want to see" post.
This video, which is part 1 of 3, is just under 11 minutes long and covers Chandler's discussion of the issue with free fall in the NIST report:
Part 2, just under 6 minutes, addresses NIST's measurement of the time of collapse:
Part 3, a little over 10 minutes, goes into Chandler's detailed analysis of the WTC7 collapse:
I'm reaching up and reaching out.
I'm reaching for the random or what ever will bewilder me.
And following our will and wind we may just go where no one's been.
We'll ride the spiral to the end and may just go where no one's been.
