Nope. I personally saw them both fall and bury my office with the collapse.

All that one needs to know, to be able to conclusively prove that the Twin Towers were demolished, is that the towers fell in roughly 10 seconds, that is, that they fell at about the same rate that an object falls through air. The observed collapse of the World Trade Centers 1 and 2 have been measured at near the rate of free fall. This is the rate at which nearly ALL of the "falling energy" (kinetic energy from gravity) must deliver the building to ground level ASAP. This leaves NO energy for smashing and pulverizing the concrete slabs NOR for shredding construction steel. Can't have it both ways! There is only so much kinetic energy available and it can either be used for shredding steel and pulverizing concrete OR it can be used for acceleration toward the ground. The building simply can't get to the ground in the requisite time that is observed unless most of the energy goes into acceleration. There is no room for a significant quantity of the potential energy being utilized in any other way than falling or the building does NOT get to the ground in time. It's a race, you see. A race against the clock.
Free fall is the unrestricted acceleration from a height toward an impact with the Earth. The WTC towers both fell to the Earth very quickly as is timed by seismographs and video. They fell at the rate of free fall; that is, they fell as though NOTHING was in their way. The speed at which they fell totally cancels the theory that they "pancaked" one on top of the other and then stressed one floor after another until the entire mass was in rubble on the ground. According to rate of collapse, the towers fell smoothly and without encountering obstruction or resistance of any kind.

no, no, no

Are you refering to the article: "Free-Falling Bodies
Simple Physics Reveals The Big Lie
Collapse Theory Fails Reality Check"

http://911blimp.com/prf_FreeFallPhysics.shtml

".......The government and the media told us what we saw. The government told us that we had witnessed a "gravitational" collapse; what is now referred to as a "pancake collapse".....

READ it, it is very interesting

The scientists who've concocted this "pancake theory" made a fatal error: they forgot to check their work! Which is an easy thing to do, even without any physical evidence to forensically examine. Anyone, at any time, can check the work of the scientists -- that incredible pancake theory of theirs -- using simple, high-school physics!

How Gravity Acts

Sir Isaac Newton noticed, centuries ago, that apples fell (down! never up...) from trees. Lots of others, before him, had also noticed this, but none had ever devised a theory of gravity from the observation. Over the years, mankind has learned that the force of gravity comes from an acceleration of known constant magnitude, depending only upon mass and separation. (That doesn't mean we know HOW it works, or WHY, but we have managed to be able to predict its effects with a high degree of precision and an even higher degree of certainty -- gravity has always had the same, predictable, effect.)

Of course, people didn't figure this stuff out immediately. According to legend, Galileo Galilei used the leaning tower of Pisa to demonstrate that a large ball and a small one (of lesser mass) fell (accelerated) at the same rate. Prior to Galileo, people had just assumed that heavier objects fell faster (much the way mankind had long assumed that the Earth was flat!).

So while an object of greater mass will exert more force upon anything which is supporting it against gravity's pull (ie, it's heavier), it does not experience any greater acceleration when gravity's pull is not opposed (ie, when it's falling). Gravity can only accelerate objects at one known, constant rate. Heavier objects are not accelerated (downward) any quicker than are lighter objects, as Galileo demonstrated centuries ago

Nothing can fall faster than the acceleration provided by gravity unless something accelerates it from the other direction, for example, pointing a gun at the ground and firing it. Even if the towers *were* demolished by explosives, which they weren't despite a previous poster's pseudo-scientific jargon, that would not cause them to fall faster, since the explosive force would be in all directions.

NO, gravitys effects travel at the same as light speed ( interesting huh) do some research and you will see. Gravitys speed on earth is the usual 32 feet per second increasing in velocity 32 feet per second every single second, until the object reaches terminal velocity - usually 150-220 mph.

I think "Billey32" has a great answer. What a go!

The answer being, NO! the towers fell at free fall rate, as shown by seismic activity recordings.

The implications of this are part of another question. Which may lead one to ask, What type of devils really orchestrated this atrocity? I wonder if anyone has asked this question on yahoo answers?

Gravity is not a speed, it is a force, which means acceleration and therefore increasing velocity, but the speed of a falling body is only limited by air resistance.

NO, it is Impossible.

What kind of force could drop all that mass faster than the speed of gravity, magnetics (sorry no)?

2006-06-16 21:18:13 · answer #8 · answered by Dan S 7 · 0 0

No it did not. I agree with the first person whom answered your question. All object no matter weight nor size, once not affected by air, fall at the same speed at roughly 9.8m/s^2 or 32 ft/s^2.

nothing falls faster than gravitational pull.
forces of the Earth and weather affect everything.
Wind, Fire, Barometric pressure.
If what you ask is true there would be no such thing as Updraft in a thunderstorm.
Or turbulence in aircraft.
