I believe those formulas were taught at grade 7 (at leat when I was at school), although admittedly, they were applicable to G-Force (9.81m/s^2, if I remember correctly) in vacuum spces.

I agree that the collapses and their processes were complicated, however, there is indeed a formula to calculate the rate at which the WTC buildings fell.
It's called Galileo's Law of Falling Bodies.
According to "The Law of Falling Bodies" as originally put forward by Galileo and still accepted by all scientists (as described in the Work Book Encyclopedia under Falling Bodies, Law of) the total distance traveled at the end of any specific time in a total vacuum is calculated by this formula:
Distance (d) = (32.16/2) x Time in Seconds Squared.
If there is any resistance encountered (as in 1350 foot tall WTC buildings), then speed and time of the falling body slows down in relation to the resistance. Thus the time of approx 10 seconds for the Towers to collapse indicates the Towers fell at approx the rate objects descend in a
vacuum with no resistance.

Anything above does not count here.

Just prior to the first collapse, the top of the South Tower tipped to 23 degrees, but then it suddenly stopped its angular momentum, changed direction and fell straight down. At this point the upper segment was hanging over the edge by approximately 65 feet.
The only way the momentum of the falling top could have been changed in mid-collapse was to blast away a portion of EACH of the 47 core columns, causing the building to fall uniformly into its own footprint. How the Towers fell is impossible according to the "official" story because the gravitational potential energy of a skyscraper is nowhere near sufficient to destroy its own frame.

Not exactly. Besides having an massive outer envelope with 236 large exterior steel columns (you call it a cage), the buildings also incorporated an enormous interior core (filled with concrete) which consisted of 47 huge steel core columns that were welded and bolted together with steel plates. Each pf these central core colums extended deep into the bedrock far below the Towers.
Furthermore, there were steel trusses which crisscrossed, making a mesh that connected every other exterior column ...along with diagonal bracing and steel rods connecting the trusses.
If the government's
theory of pancaking (the floors crashing down upon each other and causing the Towers' collapse) was true & valid, then much like a phonograph record slides down a center spindle, there would have much of the central core remaining after such a "pancake collapse."
Instead, the entire Tower structures, including the central core, was reduced to a homogenous dust cloud and a pile of chopped up steel beams.

I know that both steel and concrete are superior conductors of heat. Vibrations are not the issue here (unless you want to discuss theory into alternative technological advancements, or vibration induced destruction of morphous materials).
As for
conductivity of the solid materials in the WTC Towers, the solid steel columns and the buildings' concrete dissipated the jets' subsequent fuel fires and the heat generated locally quite quickly into other areas. This fact is supported by the people peering out of the building during the localized fires that burned elsewhere in the building.
Obviously these individuals were unaware they were touching molten steel!
Again, the gov's claim that the jet fuel fires reached temperatures high enough to melt steel is false

Newton explained that well over 200 years ago.
These are just some observations on the arguments you presented in this regard. Of course mine don't disprove the explosives theory, although personally this isn't where I would look for a proof of government's conspiracy.

Yes it is possible that the buildings could have collapsed in under 10 seconds; in fact they did. However, since we're not living in a vacuum, it's safe to assume that the WTC Towers could not have collapsed into themselves, encountering MOUNTAINS of resistance, without something removing that resistance ...namely, explosives.
Not a government conspiracy? ...hmmm, let's see:
* destruction closely resembles demolition by explosives
* military stand down on 9/11/2001
* all evidence quickly removed, shipped overseas, or buried
* numerous government statements about 911 are outright lies
* 911 Commission Report false
* important details ignored, or covered up
* etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc., etc....
Sounds like a conspiracy to me!
