That's actually quite a bit. Yes, but vibrations have also a velocity. The velocity is minimal at the turning points and maximum in between. The maximum velocity is, what I have figured out. So I can assume the building acts like a VERY large tuning fork (or similar) and this swinging is caused by the impact of a plane. And this wouldn't require wheels. > All that momentum/energy applied to a relatively small area (the frontal > cross section of a 767) is why the jets blasted into the towers rather > than bouncing off or exploding on impact or something. Energy and momentum are not the same thing. Momentum is m*v and energy is 1/2 m *v². As 'Shill #2' mentioned: "Aeroplanes. Four honking great big aeroplanes, momentum, fire, and gravity." He wanted momentum, not energy. Momentum is related to the resistance against acceleration (inertia) and cannot be 'applied to a relatively small area', since areas have two dimensions and no mass. Apparently you want to express, that the material at the impact zone has only little mass compared to the entire building and therefore could be kicked away easily. Well, thats almost true, but the jet has also little material in direct contact. And that material in contact was aluminium, while the building consisted of steel and concrete (mainly). TH
