What a Gravity-Driven Demolition Looks Like

In the previous post, professional engineer Jonathan Cole referred to the gravity-driven demolition method known as "verinage" and claimed that if one measured it's collapse, it would reveal that there was a "jolt," unlike the collapses in the North Tower and Building 7. And indeed, high school physics teacher David Chandler did just that, using a special program that measured the rate of acceleration of the collapse. The point is that in gravity-driven collapses, whether natural or man-made, if resistance is encountered there will be deceleration or a "jolt." In order to have no deceleration, the cause of resistance must be removed.

UPDATE: I thought I would add Chandler's original video, "The Downward Acceleration of the North Tower."
